Help with using CSV file in Katalon Recorder

I am experiencing exactly the same problem when trying to use a CSV file to fill a form. With previous versions I have never seen this message:

[error] SyntaxError: Unexpected token N in JSON at position 0

So I am really lost… Any light into this will be much appreciated.

Thanks in advance!

Hi @Kolebano

What version and browser are you using? This problem was already fixed in the latest version ( on Chrome. For Firefox we’re working on making the new version of KR compliant with Firefox Web Store so it may take a while.

Hi @ThanhTo;
I am using:

  • Katalon Recorder

  • Chrome version 94.0.4606.61
    The weirdest part is that using the example template (i.e;data.csv) seems to work smoothly, but using a csv that before never gave a problem is not working at all and shows:

[error] SyntaxError: Unexpected token N in JSON at position 0

So any help will be much appreciated as my intention is to go a step further and been able to automatized the gather of the data straight away to the csv. (ambitious I know).

Many thanks in advance!


Please provide me with the CSV and a minimal test case that has this issue. You can zip them and send me privately.

Don’t laugh at me but I am trying to send you a private message and it seems that I am far from being the brightest as I can’t find a way…
