SHEET EXTRACTOR
Take one useful sheet out of a workbook.
Choose a sheet, filter and sort its rows, and extract exactly that active view as CSV or JSON.
Open an Excel workbook
Your workbook stays in this browser. Choose an .xlsx file up to 50 MB.
What this tool changes
Workbook bytes stay in your browser. CSV and JSON exports contain the active sheet and visible rows. The editor writes a new value-only XLSX file; it does not preserve formulas, styles, macros, charts, or unsupported workbook metadata.
