Finished importing your data and want to see a quick preview? When you’re on the Job View page, just select Preview next to the file you’d like to take a look at.
The Preview displays the first 100 rows of data as a check that your file import was successful.
If the Preview window shows that you accidentally uploaded the wrong file, no worries, you can use the Delete File action.
When all of your files look good, you'll be ready for Channel Mappings!
