How to Convert Excel to JSON

  1. Upload your file. Drag in a .xlsx or .csv file, or click to browse.
  2. Convert. Click Convert to JSON — the first row becomes your object keys, every row after becomes one record.
  3. Copy or download. Grab the formatted JSON directly, or download it as a .json file — no email, no waiting.

Common Use Cases

  • Feeding a spreadsheet into an API or script. Turn a report someone built in Excel into JSON your code can actually consume.
  • Migrating data. Convert an exported CSV or Excel report into JSON for import into a database or NoSQL store.
  • Testing and fixtures. Turn sample data a teammate built in a spreadsheet into JSON test fixtures.
