    Excel doesn't use \n for newlines. Unfortunately, due to the format of the XML file Excel and other spreadsheets use, it is not a simple task to insert newlines within the text. To use newlines with the Datatables Excel export the following steps are needed for each cell:

    1. Use the CONCATENATE and CHAR functions to build the string with newlines, example: CONCATENATE("Line 1", CHAR(13), "Line 2")
    2. Change the cell type to formula
    3. Change the formatting of the cell to include word wrap

    This thread explains how to do this for the data portion that is exported:

    I'm not sure if the messageTop and messageBottom options support applying the styles from the style sheet in the same way the data area does.

    You can use style 55 which is built into the XSLX file generated by Buttons to cause \n to display as new lines - see the excelHtml5 documentation and also this example for how to change the style of a cell.

    I'm not sure if the messageTop and messageBottom options support applying the styles from the style sheet in the same way the data area does.

    Yup :).

    Oh - One other thing. You have to disable the stripping of new line characters in the export options for the button - otherwise they will just be removed!

    Ok, I'm now running stripNewlines: false in my excel export, but there are still no linebreaks in my messageTop. It seems like "\n" is still getting stripped. Any workarounds?

    We're happy to take a look, but as per the forum rules, please link to a test case - a test case that replicates the issue will ensure you'll get a quick and accurate response. Information on how to create a test case (if you aren't able to link to the page you are working on) is available here.

    Cheers,

    Colin
