Fill PDF forms from Excel

Typical runs: 40 certificates of completion with each attendee's name and date; offer letters for a hiring cohort; W-9 request packets for every vendor; inspection forms pre-filled with property addresses; shipping or labeling forms from an order export. Anything where the same form is completed many times from data you already have.

Mapping is by column header: you pick which column fills each field, so headers that match your field names make it quick. Radio groups take the option's export value; checkboxes take a clear true value such as TRUE or Yes. A file name pattern such as {Last name}-{First name}-certificate.pdf keeps the output organized ({row} inserts the row number, and duplicate names get a (2) suffix). Before the batch runs, you can step through rows in a preview to see exactly what each PDF will contain.

Rows that fail the form's own rules — a missing required value, an invalid email, an option that does not exist — are listed with the reason instead of silently producing a broken PDF. Runs of up to 50 rows are filled in your browser: free, no account, and neither the PDF nor the spreadsheet leaves your device. Larger runs are filled on PDFBetter's servers, split into ZIP files of up to 500 PDFs, need a free account and count toward your monthly spreadsheet fill rows (25 rows on Free, 500 on Pro and 5,000 on Business). To send each filled copy for signature instead of downloading it, Business plans include bulk send.
