Code component: add data to excel file

Hi everybody!
OS (e.g. Win10): Windows 10
PsychoPy version (e.g. 1.84.x): 2022.2.4
Standard Standalone? (y/n) If not then what?: Standalone
What are you trying to achieve?: My experiment stores the initiation times when a participant starts reading a sentence, using the voicekey code component. To save the data of this initiation time, I’ve added the code ‘thisExp.addData(‘vocal_RT’, round(vpvk.event_onset,3))’ in the “End Routine” tab of my voicekey code component. This works well and stores data in a .csv file along all other info. To facilitate data processing, I wish to record these data in an excel file. To do so, I’ve ticked the “Save excel file” box in the experiment properties.

What specifically went wrong when you tried that?: Unfortunately, the data is not appearing in the excel file. Would you have any insights as to make it work?
Thanks in advance!
