A major release bringing dozens of new functions, localization support, autofill improvements, and important fixes in v0.7.0 and v0.7.1.

We’re attending FOSDEM 26! If you see the IronCalc team around, feel free to say hi and chat about spreadsheets, Rust, or anything else.

A fresh release packed with arrays, implicit intersection, DATETIME support, UI upgrades, and behind-the-scenes fixes.

IronCalc joined 300+ innovators at HackDays 2025 in Paris to prototype La Suite Calc, a new open source spreadsheet app.

After months of development in the shadows and with the gracious support of nlNet, IronCalc reached a point of no return beginning this year.
