Reply To: Delete empty cells from Data Merge via JS

Oh I see. My suggestion does work, and so did (probably) your own first try. Nothing happened because … the 'empty' cells are not empty!

If I zoom in on the image, I can see a few tiny blue markers, quite different from the standard '#' end-of-text marker. They are also visible in the “Email” field, so apparently they get found by that GREP expression.

I suggest using something like “As*Z” — any number of spaces, and hopefully that includes that unknown marker.
