A text in a preview workflow become an integer in an Excel export.

Hello everyone,

I have an issue concerning exporting data using a workflow. When I export data to be in an Excel file, some data becomes integer instead of text (when I preview the data through the workflow using "display the data" it shows me text and not integer).

This is the rendering through the workflow displaying the data :

And this is what I have on my Excel file when export :

Do you know why this happened and is it possible to fix that ?

Thank you in advance.

Kind regards.
