Header missing from output file
Online will automatically determine if your input file includes a header record, and then check that the header is valid to then be used on your output file. On some occasions, the layout or contents of the input file will mean that the header record is determined to be invalid, and as such, will not be selected to be exported and so the header will be missing when you open your results.
This can be avoided by following the below steps:
1. When you configure your input file layout, go into the field settings on the right hand pane
2. Set the options 'Skip Header' and 'Add Header Record' to output file. This will exclude your header record from being processed and ensure that it is included in your results file.
3. If you have processed your job already without ensuring these options are set, you can add your header record to your file manually. On the results page just click on 'Output Details' which will display the output file structure, including your input header record.
4. The header for the output file can be copied from here and pasted onto your output file and each column will be named accordingly
