I am trying to run a job with a CSV file having 51 rows and 4500+ columns. However, I am encountering the following validation error:

Validation error while fetching data. Error:

    Hello @Praveen Kumar Rajendran , Thanks for using Microsoft Q&A Platform.

    Looks like there might be some rows in a dataset that may not be parsed due to characters it can't comprehend. Also, you may need to split the CSV file into smaller files and process them separately. This can help to reduce the size of the file and make it easier to process.

    Is it possible to share the code you are working to read the CSV file?

    I hope this helps.

    Regards,
    Vasavi
