Our first ever IronCalc sponsor on @github.com! Thank you @terjesb.bsky.social! github.com/sponsors/iro...
We just released v0.8 with a million new features. Dynamic arrays, conditional formatting, themes, named cell styles. See about it at: blog.ironcalc.com/2026/08/01/C... Our spreadsheet engine is getting dangerous!
IronCalc goes to Paris! We will be participating in the Hackdays with La Suite Numerique: hackdays.numerique.gouv.fr

Dear friends, I'm rejoining Redis. It's a long story, so it deserved a blog post to explain all the details: antirez.com/news/144
Folks building with IronCalc!
I made a spreadsheet app in #rust with #ratatui and #ironcalc. It was way easier than I thought it would be. The apis of both of those crates were really easy to work with. * ratatui: docs.rs/ratatui/0.29... * ironcalc: docs.rs/crate/ironca... * The code: dev.zaphar.net/zaphar/sheetui
We used the fantastic regex-lite crate from @burntsushi.net and reduced the wasm build in 1 Mb! The total js+wasm+other downloaded in the IronCalc app is 583kB. Long live lean software!
You are up to date.
