Hey @gorby San, the behavior you observe when writing to Excel is due to the Write Range activity’s built-in handling of Object types, which converts them to a string (or other compatible formats). You don’t need to manually call .ToString() in this case. However, if you’re working with the value in UiPath after retrieving it from the DataTable, you may need to cast it to its original type, especially if you need to perform type-specific operations.
