If you know how, please leave a comment below. Im not sure how to enter a new line character in Mac Excel, as a delimiter, or in the search and replace dialog. You can also use Control + J for new line during search and replace operations. Flipping the data back and forth among various file types (copying to Word, over to Outlook, then re-copying back to Excel) is bound to cause formatting issues. On Windows, you can type Control + J to enter the equivalent of a new line character for the 'Other' delimiter. But the system you describe sounds maddeningly over-engineered to me. Or you could let your supervisor write on a hard copy and you type the changes. Or your supervisor should get/learn Excel and “edit” your sheet when you turn it in. It sounds to me like your company needs the services of a good IT professional to set up some sort of environment in which your supervisor has direct access to the data that needs editing. How did you two come up with this way of doing things? Using the keyboard shortcut to get to a new line is fine if youre manually entering the data. This may sound a little harsh, but … can your supervisor not simply edit the file in Excel? Does s/he not have Excel? Or has it but doesn’t know how to use it? What’s the barrier to simply attaching the Excel sheet to the outgoing email, rather than dumping the text into the body of the email? I don’t really get how this copy-and-paste process you describe evolved. Replace a Character with Line Break in Google Sheets.
