Sure, I can help you with that! Here's how you can split one cell into multiple rows in Microsoft Excel:

1. Select the cell or range of cells that you want to split.
2. Click on the "Data" tab in the ribbon at the top of the Excel window.
3. Click on the "Text to Columns" button in the "Data Tools" group.
4. In the "Convert Text to Columns Wizard" that appears, select "Delimited" and click "Next".
5. In the next screen, select the delimiter that separates the text in your cell(s). In your case, it looks like the delimiter is a line break, so select "Other" and type in the character that represents a line break (usually it's "Ctrl+J"). You should see a preview of how your text will be split.
6. Click "Next" and choose the format for each column. If you want each line to be in a separate row, select "Text" for all columns.
7. Click "Finish" and your cell(s) will be split into multiple rows.

That's it! This method should work for any number of cells that contain multiple lines. Let me know if you have any questions or if there's anything else I can help you with.
