[**IronCalc**](https://www.ironcalc.com) is a open source self-hosted spreadsheet engine and library. It is written in rust, has minimal dependencies, and is very lightweight. The engine runs in WebAssembly in your browser, providing high-speed calculations without slowing your system.  
IronCalc provides first class bindings for python, nodejs so you can import `ironcalc` as a library and perform custom headless computations and save the spreadsheet to xlsx or icalc formats. You can also add spreadsheet logic to your SaaS apps or internal dashboards by embedding IronCalc.

### Try it out

> Visit the [application page](https://ngi.nixos.org/app/ironcalc), launch IronCalc in a shell environment, container, or NixOS VM and follow the usage instructions.

This work has been done by @phanirithvij as part of the [Nix@NGI packaging effort](https://nixos.org/community/teams/ngi), funded by [NLnet](https://nlnet.nl) under the NGI0 Commons, Core grants.

**Note:** IronCalc nixpkgs derivation is currently broken on `aarch64-linux` which we plan to fix as soon as possible.
