Frequently Asked Questions
Do I need a Microsoft 365 account or OneDrive login to edit Excel online here?
No. SheetCombine opens directly in your web browser without Microsoft accounts, cloud storage, or sign-up gates. Your .xlsx, .xls, and .csv spreadsheets stay inside local browser memory.
Does SheetCombine work on Linux, Chromebook, and ChromeOS where desktop Excel is missing?
Yes. Click Install App in the top header to install SheetCombine as an offline Chrome or Edge Progressive Web App (PWA) on Linux, ChromeOS, Windows, or macOS, and click Maximize to expand the grid to full viewport.
When I finish editing online, does Download keep my cell colors and multi-sheet tabs?
Yes. Exporting as Excel Workbook (.xlsx) writes all worksheet tabs along with cell background fills, bold/italic/strikethrough weights, font colors, alignments, and number formatting directly into the downloaded file.
