I downloaded the Data from admin module and also got the data from my panel provider. In excel I merged the datasets and saved the file as csv. When uploading the file into Lighthouse I get:
"the file contains an invalid field. 'sys_RespNum;sys_StartTime;...........(all variables)..' ERROR: The name contains invalid characters."
So similar to this problem (https://community.sawtoothsoftware.com/lighthouse-studio/post/importing-csv-data-file-in-sawtooth-lighthouse-studio-v8HxYuI4UqNH083). I choose comma separated, and also changed my PC language to English but still the same error.
I also just tried to download data as xlsx, open it in excel (not changing anything), save as csv and upload it again - same error.
Thank you!
