Excel (XLSX) to JSON converter
Turn a sheet into JSON for an app or an API: one object per row, with the column names as keys.
Accepts
Excel workbook (.xlsx), OpenDocument spreadsheet (.ods). Other file types are not converted on this page; the File Converter hub takes every kind it knows.
How to convert
- The workbook is read by the same spreadsheet reader as Spreadsheets. Formulas are not calculated: the value Excel saved with each formula is used.
- Numbers and true or false stay typed, dates become text such as 2026-10-24, and empty cells become null. Untick the column names option for an array per row.
Your files stay on this device. Nothing is uploaded: the conversion runs in your browser, and the file is never sent to PartPriced Tools or to any other server.
Questions
What about several sheets?
Choose Every sheet: the JSON is one object with a key for each sheet name.
What if two columns have the same name?
The second gets a number (Price 2), and a column with no name is called Column 3 and so on.
Can I convert an old .xls file?
Not yet. Open it in Excel or LibreOffice and save it as .xlsx or .ods first; both are read here.
Are my files uploaded?
No. The conversion runs in your browser, on this device. Your files are not sent to PartPriced Tools or to any other server.
