Frequently asked questions
Does this work for Adobe Acrobat XFA forms?+
Standard AcroForms extract reliably. XFA-based forms (dynamic PDF forms created with Adobe LiveCycle) require XFA-aware extraction tools.
What if field names in the PDF are machine-generated and not human-readable?+
The JSON keys use the internal PDF field names. Rename the keys in the JSON output to match your database schema before importing.
Will checkbox values extract as true/false?+
Checkboxes extract as Boolean (true/false) or their PDF on/off values. Normalise them to Boolean in your post-processing step.
