About Excel to CSV

Excel to CSV is for moving EXCEL data into CSV for imports, fixtures, spreadsheets, APIs, QA notes, and migration checks. The interface keeps input, validation, output, copy, and download close together so the result stays easy to inspect.

Workbook parsing happens in the browser with the XLSX library; selected files are not sent to ToolsFam for conversion.

Review headers, row counts, nested values, empty cells, and numeric-looking strings before using converted output in production.
