The .xlsx file is parsed in your browser and converted to HTML tables with basic cell styling. No server upload is involved.
Which file formats are supported?
Only .xlsx (Office Open XML, Excel 2007+). Legacy .xls binary files are not supported.
Is my spreadsheet uploaded?
No. Preview runs locally in your browser.
What is the file size limit?
Single .xlsx files up to 15 MB. Large workbooks with many formulas or images may render slowly.
