It looks and feels very similar to Microsoft Office Excel, but it's free, opensource, it has horizontal scrolling, feels more stable, UI a bit less polished, but it's full featured and it was super easy to migrate from Excel to Libre Calc, I'm happy that there is such a great alternative. There's possibility to open all Excel spreadsheets in Libre Calc and save Libre Cals spreadsheets in Excel format, so it's fully compatible, which is a great plus!

Price: LibreOffice is open-source software and completely free to use, whereas Microsoft Office requires a subscription or one-time purchase.

Compatibility: LibreOffice Calc can open and save files in a variety of formats, including Microsoft Excel formats, making it easier to collaborate with colleagues who use Excel.

Cross-platform support: LibreOffice Calc runs on multiple operating systems, including Windows, macOS, and Linux, while Microsoft Excel is only available for Windows and macOS.
