1.1.0
Updated
Excel2JSON is now called Sheet2JSON. Same app and features, and your license key keeps working.
New
Combine checked worksheets from one workbook into a single JSON, NDJSON or JSON-LD file, with each sheet's identity kept in the output.
New
JSON-LD export with your own context, an optional record type, and @id and @type columns for linked data.
Fixed
Removed the 200,000-cell limit. Exports now include every row of the sheet you loaded, limited only by available memory.
Fixed
Very large sheets no longer fail on export, and scrolling now reaches the last row of very tall sheets.
1.0.0
New
First release of Excel2JSON. Open Excel, CSV or LibreOffice files, or paste copied cells from any spreadsheet, select a range in the grid, and copy or save clean JSON.
New
Nested mode. Headers like customer.name and tags[0] become properly nested objects and arrays.
New
Five JSON layouts (objects, NDJSON with one object per line, rows as arrays, headers + rows, A1 cell map) plus CSV and TSV export.
New
Per-column type control. Keep IDs as text with leading zeros, or force numbers, booleans and ISO dates.
New
Key transforms. Rewrite headers to camelCase or snake_case.
New
Every install includes 10 free conversions with all features unlocked; a one-time license unlocks unlimited use.
New
Private by design. Conversion runs entirely on your PC; the only network request is the license check.
