Extract invoice fields into a clean CSV with ChatGPT
Upload invoices or receipts with an exact field list and get import-ready CSV rows, with MISSING written instead of guesses.
Oct 25, 2026
Extract these fields from each attached invoice: vendor, invoice number, invoice date (YYYY-MM-DD), due date, subtotal, tax, total, currency. Return CSV with that exact header. If a value is unclear or missing, write MISSING. Do not guess.
How to use it
1. Collect the invoice PDFs or images 2. Write an exact field list and output format 3. Upload a small batch to ChatGPT with the schema prompt 4. Tell it to write MISSING when a field is unclear 5. Spot-check 10 to 20 percent of rows against the source 6. Import the CSV into your accounting tool
Result
Schema-based prompt returns CSV rows ready to import; a half-day of receipt triage fits in an afternoon. Example: Input: 12 invoice PDFs. Output: a 12-row CSV with 2 cells marked MISSING.
Tips and gotchas
Human review: Spot-check a sample against originals. Pitfall: Misreads poor scans and handwriting; use enterprise tier for client data. Privacy: Use a business or enterprise tier for client documents; remove bank details you do not need. Best for: Bookkeepers, accounts payable staff (Beginner). Time saved basis: Estimate.
