How to use List PDF Form Fields
- 1. Add the PDF form. Drop a .pdf file containing AcroForm fields into the workspace. List PDF Form Fields loads the page thumbnails so you can confirm it's the form you meant to inspect.
- 2. Let it scan the AcroForm. The tool walks every field embedded in the document and reads its internal name, its field type such as text, checkbox or dropdown, and whatever value is currently filled in.
- 3. Copy the field list. The output lists each field one per line with its name, type and current value. Copy it to plan a fill-in script or to confirm a form matches an expected template.
When to use List PDF Form Fields
List PDF Form Fields is for anyone who needs to know exactly what fields a fillable PDF exposes before writing code against it. AcroForm field names rarely match the visible labels printed on the page, so guessing them from a screenshot fails. This tool reads the form's own metadata instead.
- Automating a form-fill script. You're writing a script with pdf-lib or a similar library to auto-fill a government tax form and need the exact internal field names like 'topmostSubform.Page1.field_3' instead of the printed labels.
- Auditing a template before distribution. A company sends out a fillable onboarding PDF and wants to confirm every field from a prior revision still exists with the same name before employees start submitting it.
- Debugging a broken form integration. A form-processing pipeline stopped picking up a signature field after a template update, and you need to see whether the field's name or type changed in the new PDF.
- Reverse-engineering a third-party PDF. You received a vendor's PDF form with no documentation and need to map out every field name and type before building an integration that fills it out programmatically.
