Frequently Asked Questions — PDF Table to JSON
How does the PDF to JSON converter structure the exported file?
Each visible row in your extracted PDF table is exported as a JSON object inside a clean array, using your column headers as property keys. Any edits, renamed column headers, or date/number formatting you apply in the spreadsheet editor are reflected in the exported JSON.
Can I rename JSON keys before downloading?
Yes. Select any column in the spreadsheet editor and rename its header (for example, changing 'Transaction Date' to 'transaction_date' or 'invoiceTotal'). The JSON exporter uses your updated column names as object keys.
What if I want to exclude certain PDF columns from the JSON output?
Open the 'Table' tab in the right-hand Format Inspector and click 'Hide' next to any column you want to omit. Hidden columns are automatically excluded from the downloaded JSON file.
