Cell Capacity Audit in Google Sheets

Google Sheets counts every allocated row and column toward its 10 million-cell limit, even when most of the grid looks empty. A few oversized tabs can quietly consume millions of cells and eventually block new rows, columns, or imported data.

XLKeys Cell Capacity Audit measures the exact allocated grid across your workbook, shows remaining capacity, and scans for trailing blank rows and columns you may be able to remove. It keeps a safety buffer beyond detected data and never deletes anything automatically.

Excel vs. Google Sheets vs. XLKeys

Google Sheets enforces a 10,000,000-cell workbook limit but has no built-in report showing capacity by sheet or likely recoverable grid space.

How to use it

1. Press Alt, release it, then type A, W, C (use Option on Mac).
2. Authorize the active spreadsheet if Google Sheets prompts you.
3. Review allocated cells, cells remaining, utilization, and the workbook breakdown by sheet.
4. Inspect the recommended cleanup areas, then manually delete only the unused rows or columns you have verified.
