CSV Output Displays as a Single Line Instead of Multiple Trials

What specifically went wrong?

Does anyone have suggestions on how to fix this? Thanks in advance for your help!

Check (or uncheck) isTrials When you define a loop, pay attention to the Is trials option. [image] If isTrials is checked then the data file will have a separate row for each iteration of the loop. Programmatically, the command thisExp.nextEntry() is processed at the end of each iteration of the loop. If isTrials is unchecked then any data saved during the loop will replace existing data rather than appearing on the next row. If you accidentally uncheck it you will therefore only get data fr…

Looking at your image, I think this is a problem with your excel program. It is not properly reading the file as comma-seperated values.

In excel, try going to Data → Text to Columns. Should look something like this?
