For analysis of data Can I upload per-collected data into survey123.
and do the same stat.
If the question is whether you can access the 'Analyze' functionality in the Survey123 website using previously collected data, the answer is yes. You would need to first have a feature service containing this data, and then you could utilize the option to create a survey based on an existing feature service.
You should then be able to navigate to the Analyze tab for the created survey, where all records within the feature service will be represented.
