What is the limit of settings that can be added in the Task Scheduler?

If each setting in the Task Scheduler is manually added, one by one, there will be no limit on how many settings that can be added.

If you are using a CSV file to bulk import the settings, the accepted limit of settings in the CSV is 200 lines.

If you need to import more than 200 settings, the CSV will need to be split into less than 200 settings each. For example, if there are 900 settings to import. the first 4 files will contain 200 settings, and the 5th file will contain 100.
