FAQ
Is Calculator Studio really closed?
Yes. Its notice says it was closed down on 1 September 2026, that shared and embedded projects are offline and that accounts are no longer accessible. The notice is at calculatorstudio.co/service-termination.
Can I get my calculator out of Calculator Studio?
The notice says accounts are no longer accessible, and gives a support address for questions. If you still have the spreadsheet the calculator was built from, that is enough to rebuild it.
Will my spreadsheet work in CalcForms?
Paste it into ChatGPT and ask CalcForms to build the form. Excel and Google Sheets formulas, lookup tables and nested logic work as they do in the sheet. It covers the usual spreadsheet functions, from logic, rounding and conditional sums to lookups, dates, loan math, text and statistics. A function it does not have, a custom one from your sheet's own code for example, is named when the form is built, and the form cannot be published until that calculation is rewritten.
What's the catch with the free tier?
No catch. Unlimited forms and unlimited submissions in ChatGPT, no credit card. The paid part is the web portal: the dashboard, insights, exports and branding, at $12.99 a month after a 1-day free trial.
