How to Get the Most out of Excel with Machine Learning

Excel is, without a doubt, the most used data analysis tool. Many companies around the world rely on it daily to store and organize data such as sales numbers, profit rates, expenditures, or revenues. Overall, Excel and spreadsheets are a valuable resource for any business for its simplicity and power.

But there is something that Excel can’t manage on its own: text data.

Excel’s functions can’t assign value to what our customers said in the latest customer survey wave. It’s unable to understand if our clients are happy or angry with our services. And there’s a simple reason for this: words aren’t numbers.

If we want to analyze batches of customer surveys, tweets, reviews, and the like, to identify trends and patterns within them, we’ll have to do it manually, spending valuable hours on a tedious task.

This is where machine learning comes into play.

Machine learning algorithms can automatically analyze hundreds and thousands of Excel rows with text data in a fast, consistent, and scalable way. These models can be trained to assign a specific value to words and phrases, identifying topics, keywords, entities, and even sentiment. Machine learning can help your team sift through text-filled spreadsheets, saving them time and energy.

But what exactly is machine learning? And how can you use it in your Excel spreadsheets? Do you need to be a trained programmer or have a PhD. in data science? The simple answer to these last questions is no. Anyone can train a brand new machine learning model or even use a pre-trained one, readily available online. In this article, we’ll cover all of these topics, so sit tight and read on:

Let’s get the ball rolling!

What is Machine Learning?

Machine learning is a field within Artificial Intelligence (AI) that refers to algorithms that allow computers to learn how to perform specific tasks. These algorithms can learn from examples we provide as training data.

An example of a machine learning algorithm that’s present in our everyday lives is the algorithm Netflix uses for recommendations. It shows us movies we might be interested in based on what we’ve already watched. Machine learning algorithms also power Gmail’s ability to automatically detect spam in our inbox or Apple’s virtual assistant Siri.

Combined with Natural Language Processing (NLP), machine learning models can effectively interact with human-generated content in the form of text. How? Detecting which language a particular piece of data is written in, what topics are present in a product review, or which aspects of a particular service are being mentioned within an open-ended response of a customer survey. These algorithms can even be trained to detect how positive, negative, or neutral a particular piece of customer feedback is.

How can Machine Learning help data analysis?

So can how machine learning be used to analyze data-filled Excel spreadsheets?

Let’s say you’re sitting on a spreadsheet with hundreds of open-ended responses from a recent customer survey. Getting insights from a batch like that will mean hours of manual work. Sorting each answer by topic and overall sentiment will prove to be a cumbersome task. And, in the meantime, urgent matters may come up that require your team’s attention.

A machine learning model can take care of this analysis in an easy, fast, and consistent way. Having a model analyzing your Excel spreadsheets automatically can save your team hours of valuable time and productivity. Additionally, machine learning models can take care of large spreadsheets in a matter of seconds, scaling your team’s productivity upwards.

Many hands working on the same spreadsheet analysis may often result in inconsistent results due to variations in subjectivities. One team member may think a particular survey response should be tagged as neutral, while another might deem it positive or negative. In contrast, a machine learning model will use a single criterion time after time.

Also, having a real-time analysis of your survey responses could help you quickly craft a roadmap for your company, addressing what your clients consider to be your weakest point.

So, these are the main benefits of using machine learning on Excel spreadsheets:

  • Speed
  • Scalability
  • Consistency
  • Real-time results

Now that we have seen how machine learning is used to analyze Excel spreadsheets, let’s go over the most popular machine learning techniques for text analysis. These can be grouped into two main categories: text classification and text extraction.

Text Classification

Text classification is the process through which tags or categories can be assigned to a piece of text according to its content. It’s one of the most efficient text analysis techniques companies are employing to gather useful insights from unstructured text.

Right now, we’ll explore some of the most popular text classification techniques, including topic classification, sentiment analysis, intent detection, and language detection.

Topic Classification

Topic classification is a machine learning technique with which an algorithm can group pieces of text through a collection of data and assign tags corresponding to different theme categories.

With a topic detection classifier, customer-facing teams can automate processes and get better insights from their data. For example, customer experience teams can automatically route new feedback from customer surveys according to the topic. For instance, they can automatically get results indicating how many survey responses are about their service’s price, performance or even their support team.

For example:

“Navigating through the platform’s menus is an absolute mess”

A topic classifying model can be trained to read this and tag it automatically under “UX/UI”.

Try out this pre-trained topic classification model by MonkeyLearn, designed for SaaS companies to classify NPS responses. The built-in tags here are “Customer Support”, “Ease of Use”, “Features”, and “Pricing”. Just enter your own text and click on “Classify Text”:

Sentiment Analysis

Sentiment analysis is the process through which a machine learning algorithm assigns a specific value to text pieces according to its sentiment, like positive, negative, or neutral.

A sentiment analysis model can sift through a batch of survey responses and tag them by positivity, negativity, and neutrality. This can help many companies quickly get a first glance at their latest survey’s results before actually analyzing them individually.

Another way of using sentiment analysis could be to train a model to detect negative sentiments in survey responses or support emails, to take care of those issues first.

You can try out how a sentiment analysis model works with this pre-trained model:

Intent Detection

An intent detection model can tag a text according to a set of intentions before we read them. For instance, an intent detection model can be used to automatically tag responses to outbound sales emails according to the expressed intent.

This pre-trained model can detect whether our potential customers are interested in our services or not. Subscribe, Unsubscribe, Interested, Not Interested, and Email Bounce are some tags that the models predicts:

Language Detection

Language detection is a natural language processing model which can determine which language a certain piece of text is written in.

Service providers usually have customers from all around the world, with specialized CX and support teams speaking several languages. A language detection model can help speed up the process of driving each support ticket, email, tweet or piece of feedback to the right team without having to check them manually in advance with a localized team.

This pre-trained language detection model can identify 49 different languages. You can test it with your own text and see which language it detects:

Text Extraction

Text Extraction is a text analysis technique used to extract data that’s already in the text. These elements can be keywords, product specifications, prices, and brands, but the possibilities go beyond that.

Let’s go over some of the most commonly used text extraction methods: keyword extraction and entity recognition.

Keyword Extraction

A keyword extractor can quickly let us know the most relevant words or expressions from a piece of text. These keywords can be useful to either summarize what a large piece of text is about or to get back a list of subtopics present in it.

For example, we could use a keyword extraction model in a spreadsheet containing our customer’s feedback and track how many times certain aspects of our products are being mentioned.

Let’s imagine we’re in the electronics market. Another way to use a keyword extractor would be to analyze our ICP’s (Ideal Customer Profiles) tweets or reviews to understand what sort of specs are usually being addressed by our target market.

Check out the following pre-trained keyword extraction model with your own text:

Entity Recognition

An entity recognition model is trained to extract people’s names, brands, companies, institutions, universities, and more from a text. This can be especially useful for brand monitoring, but it can also be used to analyze spreadsheets filled with customer feedback, to see if customers are mentioning the competition or other brands within their comments.

Here’s a pre-trained company extractor that identifies companies and entities from text in English:

Data Visualization of the Results

Once all the text data in your Excel spreadsheets has been analyzed, you’ll probably want to visualize the results in a way that allows you to get a clear picture of the insights.

Excel has built-in tools to create charts and graphs that are super useful for getting insights right away from the results of your analysis:

Excel Machine Learning - Data visualization

There are dozens of different charts for visualizing results on Excel, and even more ways to slice your data for visualizing different aspects of your analysis. So, it’s important to first take a moment and define the insights you are looking for. Then, the next step is to find the graph or visualization that best fits your needs.

If you are interested in learning how to do compelling visualizations on Excel, then check out this comprehensive guide.

But Excel is not the only tool for creating engaging visualizations that you can share with your team. Next, we’ll explore three popular data visualization tools that easily integrate with Excel spreadsheets.

Google Data Studio

Launched in September 2018, this is one of Google’s latest services and consists of an intuitive yet deep data visualization platform designed to create attractive presentations from our data.

With Google’s trademarked simplicity, Google Data Studio has a pretty low learning curve and can deliver static and interactive charts, graphs, and maps.

One of its distinct features is its seamless integration with Excel. Once we have connected data from an Excel file, there’s no need to re-upload it if we add data or make some changes. Google Data Studio stays connected to your data and reflects any changes in your presentations.

Last, but not least, it’s free!

Here’s a tutorial on how to get started with Google Data Studio.


Tableau has a steeper learning curve but holds a large number of integrations, allowing us to connect our data from almost anywhere. Although you’ll need a paid subscription, Tableau also offers guided tutorials and free trials to familiarize yourself with the platform. Tableau also provides useful dev tools for a more in-depth approach to data analytics.

One thing to keep in mind is that Tableau’s repertoire of charts and graphs isn’t as extensive or versatile as one would hope for. Also, it’s performance can be a bit clunky at times, but it still remains as one of the most used data visualization tools in the market.


Looker’s learning curve is at that middle spot between Google Data Studio and Tableau, offering easy-to-use interfaces and a diligent support team for any questions that might arise.

With Looker, any business can reflect insights from large spreadsheets with style and ease. Prices range depending on the customer, so there’s a personalized aspect of their service. Either way, product demos are available for anyone wanting to check out Looker before making a decision.

Looker’s branding often revolves around ‘the bigger picture’, and that’s why its platform has a pretty big catalog of visualization options and ways to integrate our data.

Here’s a handy tutorial on how to use Looker’s basic features.

Use Cases & Applications

Now, let’s go over some useful examples on how machine learning can automatically analyze the data in your Excel spreadsheets:

Customer Feedback

How many NPS responses does a company receive each quarter? Hundreds? Maybe thousands? Most customer surveys are easy to analyze, but open-ended answers are harder to batch-process because the data in them is unstructured. It consists of natural language in the form of sentences that machines are unable to understand.

With the proper training, sentiment analysis, topic classifier and keyword extraction models can automatically read NPS responses and provide accurate insights on what is being mentioned and how (sentiment).

For instance, used a keyword extractor to analyze their NPS responses and quickly visualize how many times different aspects of their service had been present in those responses:

Excel Machine Learning - NPS surveys

This graph shows that Promoter’s service is the undisputed star of their NPS score, followed closely by quality and great service. This last keyphrase is interesting because we can trust that almost every time we see it in a piece of text it will be positive.

Market Research

Brand awareness, user engagement, and prevailing trends are some of the main things a brand manager usually looks for when trying to understand the different narratives. Social media holds valuable information about your brand and your competitors.

With keyword extraction, you can quickly identify the main concerns or conversation topics approached by your target audience on social media. This process can also be done on any other unstructured text source like, for example, customer review sites such as Capterra or G2 Crowd.

In this post, we analyzed nearly 1 million hotel reviews from TripAdvisor. The results were more than interesting.

The first thing we did was to use a sentiment analysis model to divide reviews into good and bad:

Excel Machine Learning - Hotel reviews sentiment

After that, we filtered the results by city and obtained a more in-depth overview of which cities around the world receive the best and worst reviews by their customers:

Excel Machine Learning - Hotel reviews sentiment per city

The results showed that London has the overall worst reviews among other big capital cities around the world. Bangkok and Madrid hold the best records so far.

But we went even deeper. With topic classification, we were able to see which are the most mentioned aspects by these customers and in what sentiment across the different cities:

Excel Machine Learning - Hotel reviews sentiment per aspect

Based on these results, London’s hotels should urgently review ‘comfort and facilities since this aspect receives the most negative reviews in the 1 million pieces of customer feedback analyzed. On the other hand, Bangkok’s hotels seem to be doing very well in this aspect.

Parting Words

Excel is a big part of a company’s operations. It stores our data and allows us to create functions, merge information, use conditional formatting, and more. But when we need to analyze text data stored in those spreadsheets and look for trends regarding topics, keywords, and even sentiments, there’s not much Excel can do.

With machine learning, all of that stored data can be processed in a scalable, fast and easy way by a model that learns from what we teach it. We can save time and money and relieve teams of cumbersome tasks. Analyzing and tagging text data manually requires hours that could be used for other, more important tasks.

Customer experience teams, product departments, data analysts and many more can use machine learning within their Excel spreadsheets to make their jobs easier. And with the latest technology available you don’t even need to be a programming expert to do this.

If you’re interested in getting started with training your own text analysis model, check out MonkeyLearn and request a demo to get started.
