Why look for an Excel alternative?
Microsoft Excel is the standard, but it comes with real drawbacks. The $99.99/year Microsoft 365 subscription adds up. Excel can't handle files with more than 1,048,576 rows. It's slow to launch and resource-hungry. And it's not available on every platform.
Whether you're a student, freelancer, small business owner, or data professional who's tired of paying for software that crashes on your files, there's a better option.
