Spreadsheet extraction
Extract structured data from Excel spreadsheets
Send Excel files and get structured data back. The API reads across sheets, understands header rows, and maps cells to your schema — even from complex multi-sheet workbooks.
How it works
Send your XLSX file
Upload via the API or pass a URL. The API auto-detects the format.
Define your schema
Describe the fields you want as a JSON schema. The API maps your document to your structure.
Get structured JSON
Receive typed data with confidence scores and citations back to the source document.
Example request
curl -X POST https://dev.thedrive.ai/api/v1/extract \
-H "X-API-Key: your_key" \
-F "file=@document.xlsx" \
-F 'schema={"headers": ["string"], "rows": [{"item": "string", "quantity": "number", "price": "number"}]}'XLSX processing features

Reads across all sheets in a workbook. Specify which sheet or let the API find the relevant data.
Header detection
Automatically identifies header rows and maps them to your schema fields.
Formula-aware
Reads computed values from formula cells, not the formula text itself.
