What is the maximum number of Excel rows / columns that you support?
by Meelika Kivi
We support an unlimited number of Excel rows. However, we recommend splitting Excel files with more than 10,000 rows into smaller files. Please note that the processing time for large Excel files may take longer than usual.
We currently support a maximum number of 500 columns for Excel files. If you need more, we recommend deleting the columns that you do not need for the mail merge.
