Describe the spreadsheet. Get the .xlsx.
Copying a table out of a chat window loses every formula. Fulminare writes the workbook itself with openpyxl, so totals, lookups, and percentages are real formulas that update when you change a number.
Build a monthly budget spreadsheet (.xlsx) with sheets for Income, Expenses (categories: rent, food, transport, subscriptions, other), and a Summary sheet that totals each category with formulas, shows savings rate, and highlights any month over budget.
How it does it
- 01Plans the sheets, columns, and which cells need formulas.
- 02Writes the workbook with openpyxl: formulas, number formats, frozen headers.
- 03Opens the file and checks the formulas calculate.
- 04Hands back the .xlsx to download or save to Google Drive.
Start from data you already have
Attach a CSV export from your bank, store, or CRM and ask for the workbook built around it: cleaned columns, pivots, summary sheet.
Charts too
Ask for a chart and it adds one, or saves charts as images next to the workbook.
Questions
Does it work with Google Sheets?
The .xlsx opens in Google Sheets with formulas intact. Connect Google Drive and it can save the file there for you.
Can it fix a spreadsheet I already have?
Yes. Attach the file and describe what is broken or missing.
Is Fulminare free?
Yes. The free plan includes 3 live sandboxes, 200 runs / day, 100k tokens / mo, 5 overnight runs / mo — no card required.
How is this different from ChatGPT?
A chatbot tells you how to do the task. Fulminare does it: every session runs on its own cloud machine with a real shell, browser, and file system, and you get the finished files back.
