There are a few ways to remove page breaks in Excel. One way is to use the "Find and Replace" function. To do this, highlight the text that is broken by the page break and then go to the "Edit" tab and select "Find and Replace". In the "Find and Replace" window, type "^p" into the "Find what" field and then click "Replace all". This will replace all of the page breaks with a paragraph mark.
Another way to remove page breaks is to use the "Split Cells" function. To do this, highlight the text that is broken by the page break and then go to the "Data" tab and select "Split Cells". In the "Split Cells" window, select "By paragraphs" and then click "OK". This will split the text into separate paragraphs.
