Is there an option to use data from Air-table sheet in the form?

Is there an option to use data from Air-table sheet in the questioner?

I mean to use relevant information about person and present it on the form I send to him and to add his answers to other sheet on Airtable? Maybe it can be done via API??

If I understand correctly what you need, you wanted to import the data from Airtable to your form data.

This is currently not possible when using the Airtable integration.

What is possible instead is to export first your Airtable data into spreadsheet file format like Excel or CSV file, then you can import the data to your form data.
