What if a row has fewer columns than the header?

Missing values are treated as empty strings. The fill still happens; that field is just left blank in that row's output PDF.

How big can the ZIP get?

Each filled PDF is roughly the size of the template + a few KB of field overlay. 100 rows × 200 KB ≈ 20 MB. Practical limit ~500 rows on a typical laptop.

How does the Bulk-fill Form from CSV work?

Bulk-fill a fillable PDF template using rows from a CSV. The CSV header line should match the form field names (column name "first_name" fills the field named "first_name", etc.). Each row produces one filled PDF; all results are bundled into a ZIP for download. Optionally pick a CSV column to use as the output filename — otherwise outputs are numbered (row-001.pdf, row-002.pdf, …). Useful for invoice runs, certificate generation, name-tag batches, and any time you have N rows of data and one form template.

Exact match by name. The CSV column "first_name" fills the form field named "first_name". To audit the template's field names first, run List Form Fields.
