Portant Data Merge is one of my favourite AppSumo deals. Very easy to set up and it saves me so much time!
I send out documents with 10+ pages regularly that need to be individualized in several elements. Doing this manually (as I did before having Portant Data Merge) means to look through all these pages and find the spots where changes are necessary (e.g. client names, dates ect.). Now this process became so much easier: I just fill in my google sheet and press a button. That's it!
Support is also amazing. Thank you, James!
