I have a frustrating issue I cannot work out. I am using Crystal Reports to develop reports from an excel spreadsheet.
The issue I am experiencing is that whilst specific columns are formatted as Number fields in excel, they come across as string fields in Crystal. The frustraing part is that occasionally when making a new connection to the spreadsheet the fields will come accross successfuly as number fields. However, they seem to be reverting upon a subsequent opening of the CR file holding the report.
I am also getting a mapping box appearing when I refresh the data. If I attempt to map the fields correctly they all revert to string fields.
If anyone could shed some light on this for me it would be appreciated, unfortunately I cannot post the file as it holds sensitive info

As it turns out Crystal determines the field type based on the first cell in each column, I don't think it even looks at how they have been assigned in excel. In this case the first cell is blank, despite it being a number field. I guess Crystal interprets that null value as a string.
I put 1's in the two troublesome columns and the file no longer asks for re-mapping and the fields remain as numbers after a refresh of the report. Luckily we do not report all the way back to the first row in the spreadsheet so the fake data won't be an issue.
