  • Q: I imported numbers from an XLS file saved in CSV format but they lost their first digit ! Why ?
    A: If you have a file in XLS format (Microsoft Excel), during the file export into CSV format, if your numbers begin by 06XXXXXXXX, the standard XLS column format delete the 0 inside the CSV.
    For your sending to France, Metropolitan each number has to begin by 06XXXXXXX or 336XXXXXXXXX

    Tips:
    Before the export, transform your numbers column by using the custom format :
    - Make a right-click on the first cell of the column.
    - Go to Cells format -> "Custom" category
    - Enter in the "type" field: 0######### or 33########## then confirm by clicking on OK.
    - Make a double-click on the bottom right edge of the cell to duplicate automatically the format to the others cells.
    To finish, go to:
    -File-> Save as... -> File type "CSV".
    Now you can import your CSV file.
