What it does
TableConvert converts tables among spreadsheets, JSON, CSV, Markdown, HTML, SQL, XML, and other representations. An intermediate table editor supports cleanup before export.
Paste spreadsheet cells or upload a workbook, review the resulting rows and columns, then export the target representation. The editor can transpose or deduplicate data before generation. This visible intermediate table is useful when a direct conversion would hide an incorrect header row or a column shifted by input formatting.
The web converter's stated limit is 10 MB, with no registration required for its free editor and exports. Its FAQ says table conversion runs in the browser. Choose the JSON shape explicitly: object arrays, two-dimensional arrays, column arrays and keyed arrays represent different structures. Copy or download the final result after checking headers and types. The extension and professional API have separate larger-file/batch routes, so the web limit should not be applied to them.
