Privacy and limits

Files and passwords stay on this device. File contents are not sent to AllNewTools. Account and credit requests do not contain your dataset. XLSX files are supported; save legacy XLS workbooks as XLSX first. Workbook formulas are never executed or recalculated, and data exports do not preserve workbook styling, macros, charts or images. Large inputs are bounded to protect browser memory.

CSV contains values only and has no cell types or formatting. Protect formula-like text before opening untrusted CSV in spreadsheet software. Use XLSX when identifiers must remain text.
