Method, example & boundaries

PDF Form Field Inspector: from input to a reviewable result

Inventory AcroForm field names and implementation types in a local PDF without submitting values or uploading the file. The plain report is useful before integration, flattening, archival, or a handoff where unnamed and unexpected fields create risk.

Worked example: a three-field intake form

Example input
PDF fields: customer_name text, plan_choice dropdown, terms checkbox.
Example output
Three numbered rows containing each field name and its PDF field class.

How to interpret it

The report confirms the machine-facing names an integration must target without displaying or transmitting entered values.

AcroForm dictionary inspection

The browser loads the PDF, asks the form dictionary for its fields, preserves document order, and prints each field name with the field object type. It returns an explicit no-fields result when the AcroForm collection is empty.

PDF form boundaries

  • Dynamic XFA forms are not equivalent to standard AcroForm fields and may not appear.
  • Encrypted, damaged, or permission-restricted PDFs may fail to open.
  • A field inventory does not validate business rules, JavaScript actions, tab order, or accessibility labels.
