Is it possible to add/modify existing cards WITH powerups by email or another outside-of-trello way?

Hello,
I am using the "Custom Fields" power-up in my board and looking for a way to add or modify cards via other access route than doing things manually on trello.com. I am currently working on a script that would import data from an excel file, that I created, to trello.com board. I am aware of the possibility of adding new cards via e-mail, however it doesn't allow for modification of existing cards and it isn't possible to add cards with custom fields specified.

@Nexon44444 are you tied to Excel? If you're open to using Google Sheets you can use the Trellinator library to create cards from a sheet. For example the following would grab a bunch of rows and create cards from them:

The expected format is list name, card name, card description then any number of custom field values. If the Custom Fields power up is not enabled it will be enabled, and any missing custom fields will be created automatically.

You can see how to set up Trellinator here:
