BIDICALC is a bidirectional calculator, a spreadsheet where formulas also update backwards.
In any normal spreadsheet, when you change values that are the input to some formulas, the outputs are automatically updated. What if it worked the other way? What if you could... change the output and see the input automatically update to match the formulas? This is what bidicalc does!
Bidicalc is written in TypeScript and entirely open-source under the AGPL licence. This means that you can freely reuse, modify, and share bidicalc as long as you make the complete source code of your modified version available under the same licence. If you are interested in buying bidicalc under a different licence please get in touch.
