    Solution Accepted
    Hi @Loan_Nguyen56 please open you file with excel and remove all the columns after the last data point. I had the same problem opening it but deleting the blank columns and the blank rows fixed the problem. That happens if you open it with the upload assistant.
    You woun't have the same problem if you use the read excel operator.

    I guess you can't simply share the file with us?
    But can you say if there are any unusually cells in the file? My first guess from the error message would be, that there is a problem parsing some numbers in a cell.
