Hello,

I am using this workaround [url] manual.limesurvey.org/Workarounds:_Furth...le_Drive_Spreadsheet [/url] to import the data. With the columns with default names it works perfectly. Please could you tell me which expression I should use to import the answers of the questions (578448X10X60 & 578448X10X61): [url=https://prnt.sc/15jnn5m ] prnt.sc/15jnn5m  [/url]

Thanks for your help, best regards,

Problem solved: the error occurred because the StartTag started with a number (578448X10X60) I changed it to the name of the question (P01) and there was no more error.
The XML has authorised characters for the beginning of the StartTag: [url] www.w3.org/TR/xml/#NT-NameStartChar [/url]
