Convert JSON to CSV Online — Arrays to Spreadsheets — NeedAnyTool

Product wants a spreadsheet. Engineering handed you a JSON array of users. Opening it in Notepad won’t help — you need columns.

JSON to CSV maps object keys to headers and rows to lines. Flatten nested objects carefully — deeply nested JSON often needs a cleanup pass in JSON Formatter first. Conversion stays on your device.

Best-fit JSON shape

  • Array of flat objects with shared keys works best
  • Mixed keys produce sparse columns — expect empty cells
  • Nested objects may stringify or need flattening before convert

Steps

  1. Validate/pretty-print with JSON Formatter if needed.
  2. Open JSON to CSV.
  3. Paste the array.
  4. Download or copy CSV into Excel / Google Sheets.
