How to Use Excel to JSON Online (Free)

Excel to JSON is a free online spreadsheet tool on FileToolsHub. Convert Excel (.xlsx/.xls) worksheets into a JSON array of row objects — ideal for API fixtures, imports, and frontend mocks.

Open the live tool at /tool/excel-to-json when you are ready to start. Typical flow: Upload an .xlsx or .xls file with a header row on the first sheet. FileToolsHub maps each data row to a JSON object using those column names. Download the .json file or copy it into your API, script, or editor.

Why people use it: API-ready row objects; No desktop Excel macros required; Works beside CSV/Excel converters on FileToolsHub. Upload only what you need, then download the result — FileToolsHub removes temporary files after processing.
