The maximum number of rows in a Microsoft Excel 2010 worksheet is 1,048,576 rows. This limit has been in place since Excel 2007 and applies to Excel 2010 as well as later versions like Excel 2013, 2016, 2019, and Microsoft 365. The number 1,048,576 is 2202^{20}220, reflecting the largest number representable in twenty bits, which is a technical design choice for Excel's grid size. Alongside this, Excel 2010 supports up to 16,384 columns per worksheet
. Older Excel versions, such as Excel 2003 and earlier, had a much smaller limit of 65,536 rows (2162^{16}216), but this was increased to accommodate larger data sets starting with Excel 2007
. If a dataset exceeds the row limit, Excel will truncate any rows beyond 1,048,576 when importing or opening the file. Users dealing with larger datasets often need to split data across multiple worksheets or use alternative tools designed for big data
. In summary:
- Maximum rows in Excel 2010: 1,048,576 rows
- Maximum columns in Excel 2010: 16,384 columns
- This limit is consistent across Excel 2007 and later versions
This is a hard limit imposed by Excel's design and system resource constraints.
