Automating PDF AcroForm filling works by converting forms to reading-order Markdown with {{tag_N}} placeholders, applying a structured data plan, and writing values back into the PDF using deterministic PyMuPDF operations.

Verifying PDF form fields after data entry works by re-rendering the filled PDF back to Markdown and comparing the extracted values against the original input data plan to ensure accuracy.

PyMuPDF supports filling multi-page government, tax, and insurance PDF AcroForm fields by parsing layouts, generating tag-based plans, and applying updates across complex document structures.

Testing PDF form filling without modifying the original file is done using a dry-run mode, which parses the AcroForm, generates the tag-based plan, and validates the data mapping without applying changes to the PDF.

Converting a PDF form to Markdown with placeholders works by parsing the AcroForm fields, extracting text in reading order, and inserting {{tag_N}} placeholders to create a structured, mappable data plan.

PDF form filling automation fails on certain AcroForm fields when the reading-order Markdown parsing cannot accurately map {{tag_N}} placeholders to the corresponding data plan keys.
