AppSheet can automatically create email templates with just a single click, and all the column names are added to the template:
And you can manually edit the template to show before/after values:
But if you have a huge table with 100 columns and want to list ALL the before/after values, it’s going to take a lot of manual setup.
I’ve automated this with a template generator.
Just paste in the header row from your table, and then copy the output back to the email template.
The sheet is public, so anyone can make a copy and use it with their own tables.
