In order to effectively import data into topshelf, spreadsheets must be in a .CSV file format, cannot be open in another application, and have the expected number of columns and expected type of data contained in the fields of the SNAP import job. When creating a job in SNAP, there are required fields and optional fields that can import data into SNAP. The fields can be seen in yellow.matchingsnap.PNG

If you have headers in your document, check the "My CSV has Headers" box. The headers must match left to right in the CSV to top to bottom in the SNAP job. Hitting the match headers button will match the headers to the fields regardless of order. If columns don't match or there is extra information (i.e. a blank column in excel) the job will error out and you will have to edit either the SNAP job or the spread sheet.
