Excel to JSON
Convert Excel (.xlsx/.xls) worksheets into a JSON array of row objects — ideal for API fixtures, imports, and frontend mocks.
Quick answer: Excel to JSON lets you convert Excel (.xlsx/.xls) worksheets into a JSON array of row objects — ideal for API fixtures, imports, and frontend mocks. It is free on FileToolsHub with no account required for everyday use.
About Excel to JSON
Excel to JSON on FileToolsHub converts the first worksheet of an .xlsx or .xls file into a JSON array of row objects. Column headers become keys — the shape API developers and frontend teams expect for fixtures, seed data, and one-off migrations.
Upload the spreadsheet, process it, and download .json. Keep a header row, avoid merged title cells above the table, and move the sheet you care about to the front of the workbook before converting.
After conversion, open JSON Formatter if you want indented output, or JSON to Excel if you need to round-trip back to a sheet. CSV to JSON and Excel to CSV sit nearby when your source format differs.
FileToolsHub keeps this converter free and unlimited for everyday datasets so you are not blocked by desktop macros or one-off scripts when a stakeholder drops an Excel file into chat.
