@candimk for specific styling such as this, you can use the Text Control parameter in the Writer Feature Type and set it to Wrap Text. You can find this parameter by opening the Excel Writer Feature Type, setting Attribute Definition to Manual, and clicking Edit...
I tested this in a very simplified workspace and was able to get what you're asking for working.
You will need to make sure that your attribute is formatted with breaklines present. This way, FME will know how to wrap the attribute when writing it out to the Excel sheet. This screenshot is what I used.
If the data you're bringing in is in a set of different attributes (i.e. name, address, city, country all as separate attributes). You could use a StringConcatenator to group the attributes together into one attribute, setup like so:
I attached my simple workspace to this comment as an example.
Hope this helps answer your question!
Thanks, this is what I ended up figuring out. I was hoping to be able to have each on their own line, but my end user said they could work with the wrapped text. So not too concerned. Thanks for the xls formatting tip. I had it set up as wrap text in the template, but it didn't seem to work.
