What predefined data fields can I add?
There are four kinds of data fields you can add:
1. Current date & time
This data field means the extraction time when the data line is being scraped. For example, if you have a scheduled task that runs every day, and you would like to know the date on which the data lines are scraped, you can simply add this field.

Tips! 1. You can reformat the date with Refine extracted date/time 2. Adding the current time in Cloud extraction can help to keep all the duplicates: Can I keep the duplicates extracted in Cloud? 3. The time in Cloud extraction is based on UTC time. |
to change the format of the current time field.
2. Add a fixed value
This option allows you to create a fixed value for every data line.
1) Choose "Fixed value" from the menu
2) Enter the field name or choose from the "Common fields", then enter the fixed value you want to add
If you need to add a blank field, just leave the "Enter Text" box empty.
3. Add "Page-level data"
You can check the details at Scrape page-level data (meta data, page URL, page title, source code)
4. Capture data on the page
This option will guide you to capture other elements you want to capture on the screen.
