I am trying to use a database manager called FileMaker 12 Pro to import a large Excel 2010 table into it. The file does import the data nicely, and the field headings from Excel 2010, using the FileMaker creation facility do show up as the new field names. The problem is that in the transfer from Excel 2010 to FileMaker 12, the field headings as they appear in FileMaker now have an underscore before the field heading (as: _field heading). This is incorrect but no matter how many times I do it, the _ still appears. FileMaker tech support can find no reason that this should happen and says that it is not their product that is causing the problem. I also tried, on the theory that perhaps something was wrong with the Excel structure, to cut-and-paste the data from the original Excel file into a new Excel structure to see if that would export differently; it didn't. When I was talking to FileMaker tech support they asked me to try a simple test using about a half dozen cells and converting it to FileMaker. This worked fine with no underscores visible. I don't think it has anything to do with the problem, but it is a very large spreadsheet, consisting of about 1500 columns across and about 100 rows down. Since FileMaker is the only product that I could find that could handle this many fields in one table, I would like to try to get this to work. The error involved (the _) is certainly not fatal, just cumbersome and requiring unnecessary/extraneous keystrokes that I would like to avoid having to do. Any help offered would be appreciated and points awarded. Thanks.
