Hi there,
I import from Excel all the time. If your trying to import into Access from a file created in Excel, then you should be able to open Excel in Excel and Save As "CSV" (Comma demlimited) (which imports much more cleaner than as a regular excel).
Also, make sure that your header (column headings) is the 1st line in the data, e.g. no report titles, etc. in Excel file.
Last, make sure no breaks in columns occur or errors would occur.
Hope this helps.
