How-to reference cells from another file

Hi,
Using the spreadsheets, I’d like to know how to reference a cell from another file?
I cannot find this feature in your documentation. The Google Sheets equivalent would be IMPORTRANGE.

Thank you!

Hello @FDavid

Please see this guide on how to add external links to reference cells in our editors:

Note : in the online editor, the ability to insert data via an external link must also be implemented on the integrator side (e.g., in a third-party document management system).
