With lembot, you can choose between extracting all the CSV or only a set of columns.
This has 2 major advantages:
When you select columns, the export stay consistent over time. So does your formula 😉
While creating or editing a bot, click "Select Columns".

The columns in the CSV are automatically detected and displayed in a table.
Choose the columns you want to extract.
💡 Tip: use your keyboard to navigate easier in the table.
Click "Continue" to confirm your selection.

Visualize your selection.
Click one of the input to edit your selection.

Click "Run export" to only export the selected variables to your Google Sheets.

As you can see on the right, the sheet has only 4 columns as requested: email, sentStep, sentAt and interestedAt.
Cheers,
