How to export/import the data typed in from/to all textInput boxes?

Hi
I apologize in advance if this is not the right category. I just joined both this forum and developing with Retool and it's not clear to me which category this questions fits bests among those in the list of categories.

As for my question, here the details:

  • Goal: Writing an app that will collect configuration data for a building yet another app, albeit a mobile one. The config data will be input manually, yet it's a large amount. Thus users need to be able to "save" all data provided so far and "continue" next day.

I am building and will be running the app from an in-house self-managed Retool server.

In Retool I've seen the option to add an export event handler to a button and I tested it by downloading a full table. The output is great: csv, json,...

However, I don't know how to make it export the values of several different textInput boxes at once. This would be the "save" part I mentioned above.

Furthermore, It's unclear to me how could I import those values back into their corresponding textInput boxes (the "continue" part).

Are both things possible in Retool? Maybe only through transformers?

I would appreciate any help on this.
Thanks.
Cheers,
MA
