- Product
- Excel for the web
- Device & OS
- not provided
- Scenario
- Editing workbooks hosted on SharePoint Online or Box that were originally formatted in the desktop version of Excel.
- Observed behavior
- Partial in-cell formatting, such as bold and strikethrough text, is removed immediately after a cell is double-clicked.
Ensure you have a backup of the original workbook opened in the desktop version of Excel, as some complex formatting is easier to repair offline.
Reapply Formatting using Format Painter
Use the Format Painter tool to copy stable formatting from another cell and eliminate problematic characters like apostrophes.
Excel for the web can occasionally struggle with partial in-cell text formatting applied via the desktop app. Copying the format freshly within the web app can reset the cell's rendering behavior.
Select an unaffected, empty cell and type a test character. Apply the desired bold or strikethrough formatting to this character.
Keep the test cell selected, go to the 'Home' tab on the ribbon, and click the 'Format Painter' icon.
Click and drag over the cells that have been losing their formatting to apply the copied format.
Click on the affected cells and check the formula bar. Delete any unnecessary leading apostrophes if they exist.
Double-click the newly formatted cells in Excel for the web to confirm that the bold or strikethrough formatting remains intact.

Unmerge and Reformat Cell Ranges
Large merged cell ranges (such as 15 columns by 1 row) can trigger rendering bugs in the web version.
