Frequently asked questions
Which spreadsheet formats are supported?
Both modern .xlsx and legacy .xls workbooks are supported, along with other formats the SheetJS engine reads. Each is converted to plain CSV entirely inside your browser.
What if my workbook has several sheets?
A sheet picker appears so you can choose which tab to export. The selected sheet is converted to CSV, letting you extract exactly the data you need.
Is my spreadsheet uploaded?
No. The file is read and converted locally in your browser. Your workbook never leaves your device, so confidential financial or HR data stays private.
How are formulas exported?
Cells are exported as their calculated values, matching what you see in Excel, so the resulting CSV contains results rather than formula text.
Are commas inside cells handled?
Yes. Values containing commas, quotes or line breaks are quoted correctly per the CSV standard, so the output re-imports cleanly into any spreadsheet or database.
