Best Free & Open-Source Alternatives to Microsoft Excel


Not everyone needs Excel. Some people just want to track grocery costs. Others need a tool for work or business. Others may also need the Excel tool itself. However, affording the premium version has become a limitation to what they need the tool for.  Whatever your reason, there are free spreadsheet apps out there. Many of them are great and easy to use. Most of these alternative applications also offer certain important features that may not be available in Microsoft Excel for free.

Spreadsheets are a big part of life now. People use them to manage money, track goals, or work with large amounts of data. Microsoft Excel is still the most popular one. But it costs money. And you need to use Microsoft’s software with it.

Free alternatives are worth checking out if you want to save money or have more control over your tools. Most of them work on Windows, Mac, and Linux, too.

Excel Still Rules in Business

Excel is still the top choice for many businesses. It works well with other Microsoft tools. It also has powerful features.

People love Excel because:

  • It’s easy to use if you’ve used it before.
  • It has pivot tables and macros.
  • You can write scripts using Visual Basic.
  • It connects to other data sources.
  • It makes nice graphs and charts.

But not everyone needs all of that. If you don’t use Excel every day for work, you might find that a free tool does the job just as well.

1. LibreOffice Calc – A Great All-RounderMicrosoft Office Alternative

LibreOffice Calc is part of LibreOffice, a free office suite. It also includes tools like Writer (for documents) and Impress (for presentations).

What it offers:

  • It opens and saves Excel files.
  • It has charts, pivot tables, and formulas.
  • It works with scripts in Basic, Python, and JavaScript.
  • It runs on Windows, Mac, and Linux.

  • Make charts with Matplotlib and Seaborn.
