About this tool

Convert an array of JSON objects into CSV locally. Columns follow first-seen property order; missing and null values become empty cells.

Common uses

  • Export flat API records for a spreadsheet
  • Quote commas, quotes, and multiline strings correctly
  • Reject nested objects and arrays instead of producing ambiguous cells
