Before you start

  • Use unique non-empty column headers when exporting JSON. Merge files only when their headers match.
  • Leading zeros are kept as text. Formula-looking CSV values are escaped to reduce spreadsheet formula injection.
  • Use a phone or mobile header for Indian number formatting. Data-row, column and PDF table limits are enforced.
