Q: I try to export data from Octoparse but why is there a field missing in my data file?
A: This happens when you add a new field to the task and start a new run without clearing the previously scraped data.
When you export data in Octoparse, the export is based on the data schema that was generated during the first run of your task. If you add a new field after the first run and then start another run without clearing the existing data, Octoparse will continue to use the old schema. As a result, the new field will not appear in your export.
How to fix this
If you want the newly added field(s) to be included in the export:
Clear existing data for the task.
Run the task again so Octoparse rebuilds the data structure with the new field(s).
Now, export your data and you will see all fields, including the new ones.
💡 Tip
To avoid confusion, always clear old data whenever you update the fields in a task and want to restart it. This ensures your exported file matches the most recent task design.
