Excel: what it is really used for, what it can do for business, and its big 'no thanks'

By La Formula Magica Tech - Gianluca Bonomo

Excel is one of those tools that almost everyone uses, often every day, but not always for what it does best. And here lies the point: when used the right way, it becomes a powerful machine to manage, analyze, and present data. When forced to do other things, you risk turning it into an endless source of complications.

It is therefore worth clarifying once and for all what Excel is used for, where it gives its best, and also what the most common improper uses are—those that make us smile but in the office can cost time, energy, and quite a few headaches.

Let's start from the basics: Excel is born to work with numbers and data

The core of Excel is simple: organizing information, making calculations, identifying trends, and helping to make better decisions. It is not just a sheet with rows and columns. It is a tool that can transform scattered data into useful information.

This means it is not only useful for adding up a few figures at the end of the month. If used well, it can become a concrete support for operations, management control, planning, and reporting.

Its value grows even more in business, where numbers, stocks, sales, costs, and forecasts must be kept under control continuously.

How to use Excel the right way

1. Tracking sales and products in a shop

Let's take a very concrete example: a clothing store. With Excel, you can record sales performance day by day and understand clearly which items are really working.

It's not just about knowing how much has been sold. The real advantage is seeing which items sell quickly and which remain stuck in the warehouse or on the shelves.

This allows you to:

• understand which products are in highest demand;
• avoid useless reorders on low-demand items;
• intervene in time on bestsellers before they run out;
• plan purchases and assortment better.

In practice, Excel can help you understand when it is time to reorder that product everyone is looking for, and when instead it is better to stop before filling the warehouse with non-rotating merchandise.

2. Managing inventory with useful alerts and controls

Another field where Excel can do its job very well is inventory management. The pharmaceutical case is particularly clear, because keeping an eye on stocks and expiration dates there is not a convenience, but a necessity.

With a well-made structure, Excel can report items running low and highlight those close to expiration. In essence, it can function as an always-on reminder that draws attention before a problem occurs.

The advantages are clear:

• reduce the risk of running out of important items;
• keep sensitive expiration dates under control;
• sell urgent products first;
• organize reorders better.

This is one of the most underrated features of Excel: it doesn't just record data, it can help prevent errors and oversights.

3. Financial analysis without making life complicated

The word finance, for many, immediately causes a bit of sleepiness. Yet Excel manages to make this work much more accessible than it seems.

If you have to evaluate an important decision, such as opening a new store, Excel can help build a credible numeric scenario. You can estimate costs, payback periods, margins, and the point at which the business begins to make a profit.

The beauty of it is that it also allows you to compare different scenarios. For example:

• what changes if the rent goes up;
• what happens if sales grow faster than expected;
• what the impact of fixed costs or staff is;
• how the result varies in more conservative or optimistic scenarios.

It is not magic, obviously. But it is a very concrete way to simulate different possibilities and make decisions with greater awareness, based on numbers and not impressions.

4. Analyzing seasonality and performance in e-commerce

For those working online, Excel can become an excellent ally also on the sales and marketing front. In an e-commerce, in fact, it is essential to understand how products behave over time.

With the right data, you can identify:

• the products in highest demand during certain periods of the year;
• the differences between seasons, promotions, and demand peaks;
• the effect of advertising campaigns on sales;
• the times to prepare for an increase in orders.

This analysis allows you to improve organization, plan warehouse stock better, and read the relationship between marketing and results with more clarity.

If, for example, you know in advance when the busy periods will arrive, it becomes much easier to prepare operationally instead of constantly chasing emergencies.

5. Automating repetitive tasks

Here, one of the most useful qualities of Excel comes into play: automation. Many tedious and repetitive tasks can be managed much faster once the file is set up correctly.

Think of tasks like:

• generating invoices;
• checking payments;
• creating periodic reports;
• updating recurring summaries.

Every time an activity follows the same logic, it is worth asking if Excel can lighten the load. Because the time lost manually repeating the same step dozens of times is exactly the kind of waste that this tool can avoid.

When a sheet is well-designed, it works almost like an untiring assistant: it takes the data, sorts it, calculates it, and returns the result consistently.

6. Creating interactive dashboards and panels

Another very smart use of Excel is creating dashboards, i.e., control panels that gather the most important indicators in a single place.

Let's imagine the case of a restaurant chain. A good Excel file can show immediately:

• the performance of individual locations;
• the most ordered dishes;
• which branch has the best margin;
• how much is being spent on staff;
• where critical issues or opportunities are emerging.

The value of a dashboard lies in the speed with which it makes complex information readable. Instead of opening ten files and comparing numbers by hand, you have an operational summary immediately available.

The real strength of Excel: turning data into decisions

If you look at all these examples together, one thing becomes very clear: Excel is not just an archive of numbers. It is a decision-making tool.

It is used to understand better what is happening, predict scenarios, highlight anomalies, and simplify processes that would otherwise take more time and involve more errors.

In short, Excel gives its best when used to:

• manage data in an orderly fashion;
• analyze information and find useful patterns;
• present results in a clear format;
• automate activities that repeat;
• support operational and strategic choices.

How not to use Excel: the cases where it's better to say no, thanks

And now comes the most amusing, but also highly instructive part. Because yes, Excel is versatile. But versatile does not mean suitable for everything.

There are creative uses that make us smile, and others that seem ingenious but are actually terrible ideas. The problem arises when we try to transform Excel into something it is not.

Excel is not a text editor

Writing letters, long texts, or page-formatted documents inside cells is a classic example of forcing it. Can it be done? Technically, yes. Is it convenient? Absolutely not.

Cells were not born to write structured documents. If you need to draft a text, there are much more suitable tools for layout, formatting, and content management.

Excel is not a graphics program

Coloring cells one by one to create drawings or portraits might be curious as an experiment, but it is certainly not a sensible use in a professional setting.

For images, illustrations, and graphic works, there are software programs designed specifically. Excel can produce charts of data, which is a completely different thing. But it does not start as a design tool.

Excel is not a video game

Every now and then, someone manages to recreate games inside Excel using formulas, conditional logic, and a good dose of persistence. From a technical standpoint, it's even fun, but that doesn't mean it's a smart use of the program.

Just because something is possible doesn't make it automatically useful. And above all, it doesn't make it productive.

Excel is not a social network

The idea of turning every cell into a post might be funny as a joke, but it gets the concept across: not everything needs to go through a spreadsheet.

When there are platforms born for a specific purpose, often the best choice is to use those instead of building improbable solutions inside Excel.

Excel is not the ideal place for overly complex booking systems

This is perhaps the most realistic case among those mentioned. Creating a reservation system for a restaurant with dozens of interconnected sheets might seem like an ingenious homemade solution, but it often quickly turns into a maintenance nightmare.

The more connections, exceptions, and manual steps increase, the more fragile the file becomes. In these cases, it is better to stop and ask if it wouldn't be better to adopt a specific software.

The principle is simple: Excel is excellent for managing and analyzing data, but it must not necessarily become the universal container for every business process.

When to choose Excel and when to choose another tool

A good criterion is this: use Excel when the problem concerns numbers, tables, controls, analysis, reports, and relatively structured automations.

Instead, it is better to evaluate different tools when you need to:

• write complex documents;
• do professional graphics;
• manage social platforms or communication;
• build very complex and critical operating systems;
• use applications already designed for a specific task.

The point is not to dismiss Excel. On the contrary. It means respecting its strengths, because that is exactly where it offers the maximum value.

The best way to leverage Excel

If you want to get concrete results, you don't need to start with the most complicated things. The most sensible path is to learn the basics well and then gradually build more advanced skills.

This approach allows you to:

• avoid messy and unreliable files;
• understand which functions you really need;
• automate only what makes sense to automate;
• create useful tools for your work or business.

Excel is a bit like the Swiss Army knife of business. It is versatile, reliable, and tremendously useful. However, just like any serious tool, it works well when you use it for what it does best.

In short: perfect for working with data, much less for using as a hairdryer.
