Step 2 of 4 Spreadsheet & UTF-8 CSV

Export Clean UTF-8 CSV Headers That Match Your PDF Fields

When your CSV header row matches your PDF field names, FormBatch maps every column automatically without manual drag-and-drop configuration.

  • Export your sheet from Excel, Google Sheets, AppFolio, or HubSpot as 'CSV UTF-8 (Comma delimited)' so accented names render cleanly.
  • Include a unique identifier column (like recipient_id, unit_number, or vendor_id) to guarantee unique output filenames in your ZIP archive.
  • Pre-format dates (e.g. 2026-11-01) and currency strings (e.g. 4,800.00) in your spreadsheet exactly as they should appear on the page.
