AI Spreadsheet Generator
Describe the workbook you need — a budget, a cohort model, a commission plan, a weekly report — and the AI spreadsheet generator builds the column schema, the formulas and the checks, then produces a real XLSX. The builder below is a live demo: it writes the spec in front of you, with no file and no account.

Your prompt
Analyze the spreadsheet I attached. The data is sales orders. Scope - Group by: Monthly - Metrics: Net revenue, Period-over-period growth - Break down by: Region, Product Output - A summary table with period-over-period change - Charts for the headline metric and the biggest breakdown - Export: XLSX workbook Guardrails - Reconcile totals against source rows - Show the formula behind every number - Never guess currency, timezone or units
Starter spreadsheet
The columns and formulas this brief implies. Download it as a CSV and open it in Excel, Numbers or Google Sheets.
| Column | Type | Formula draft |
|---|---|---|
| Month | Text | — |
| Net revenue | Number | =SUMIFS(Orders[Net],Orders[Period],$A2) |
| Period-over-period growth | Percent | =IF(ROW()=2,"",IFERROR(B3/B2-1,"")) |
The prompt and the starter file are generated in your browser. Nothing is sent anywhere until you open the workspace.
From a sentence to a workbook
- Describe the subject, the period and the breakdown in the fields below. The generated column schema updates live — that is what the agent receives.
- Choose the metrics: totals, period-over-period change, share of total, rank, running total.
- Choose the outputs: XLSX with live formulas, charts, a CSV extract, an HTML report.
- Download the schema as CSV to sanity-check the structure before spending a run on it.
- Open the workspace to generate the real file. The agent fills in the formulas, formats the sheet and returns the workbook plus the charts.
What teams use an AI spreadsheet maker for
- Recurring reports: a weekly or monthly sheet with the same structure, rebuilt against fresh data without re-deriving every formula.
- Model scaffolding: a budget, a hiring plan or a pricing model laid out with the right columns and formulas before anyone touches a number.
- Cleaning and restructuring: turning an export with merged headers and blank rows into something a pivot table can actually consume.
- Handover: producing a sheet a colleague can audit, because the formulas are present instead of the values being pasted in.
Why formulas, not values
A generated workbook whose cells contain pasted numbers is a dead end: nobody can see how a figure was reached, and the sheet cannot be rerun next month. ToCharts writes live formulas into the XLSX and keeps the intermediate tables, so the result is inspectable, editable and reusable. That is the difference between a demo and something you can put in front of a finance team.
What to have ready
- Either a source file (XLSX, XLS or CSV) or a clear description if you are generating from scratch.
- The metric definitions — net or gross, which date column, which rows to exclude.
- The period grain: day, week, month or quarter.
- The delivery format: a workbook, a set of charts, a report, or all three.
Frequently asked questions
Can it generate a spreadsheet without an input file?
Yes. Describe the structure you want and the agent generates the sheet, the formulas and sample rows. Attach a file when you want the real numbers filled in.
What formats does it export?
XLSX with live formulas, CSV, PPTX slides and an HTML report. Charts come out as part of the workbook and as standalone images.
Do I need an account?
The builder on this page is free and needs no account. Generating the real workbook runs in the ToCharts workspace and uses an EndTo account.
How is this different from asking a chatbot for a table?
A chatbot returns text shaped like a table. The generator returns a workbook: typed columns, live formulas, formatting, charts and reconciliation checks you can audit.
Can it handle a messy export?
Yes, within reason. Say where the real header row is and which sheets to ignore; the agent reports what it dropped rather than silently skipping rows.
