Import csv or txt, first line as column name failed

Hello,

When I import a csv or txt file, the first line is not recognized as column name, though in Python code it works perfectly.

In DSS, after the import, I have :

- In first line, I have col1, col2, etc

- In second line, the true name of the column as they are in the original csv/txt file

- Starting from third line, I have the rows

What is the solution to import a csv/txt with the appropriate col names ? I could not figure it out.

Thanks and kindest regards

    Hi Laurent,

    You should be to adjust which line the true column names are on. Using "Skip First Lines" options. You can set that to 1 and user check Parse Next line as column headers.

    If my .csv file is

    column1,column2
    actual_name,other_name
    some_value,some_value

    This is what I would see :

    Let me know if that works for you.

    Thanks,

    If you already have a dataset you can go settings and Format/Preview Tab. To get these options.

    Additionally, you can reach this page when you create a dataset from a file there will be the Preview button once you import the file.

    Let me know if you still have issues finding these options.
