What is IronCalc?

The democratization of spreadsheets. Empowering everyone with advanced, open-source spreadsheet solutions.

IronCalc is a spreadsheet engine and ecosystem:

  • MIT/Apache 2.0 licensed: You can integrate it into your projects, customize it to your needs, and share it openly without any restrictions.
  • Feature rich: You shouldn’t worry that this or that function is not supported.
  • Excel compatible: We at IronCalc are in awe of the software created by Microsoft over the years. We want every one to be able to use their spreadsheets.
  • Fully tested: Modern programming practices should be used covering with tests any feature of the system.
  • Fast and lightweight: The programs shouldn’t be heavier than a few hundred kilobytes.
  • International from day one: Language should not be a barrier to use a spreadsheet.
  • Well designed: It should be nice and friendly to use. Designed with love from the ground up.
