Hello @Teetat Karuhawanit , Thanks for your time and patience throughout this issue.
This error is due to the content size of the Excel file is exceeding the limit set by the service.
To manage file size in Excel, begin by checking the content size, as it varies with different files. Consider reducing the data volume if necessary. If the file remains too large, try to divide the Excel file into smaller ones.
The product team is working on improving the error message. Sorry for the inconveniences that has caused.
I hope this helps.
Regards,
Vasavi
