Hi Eric,
Assuming that you're exporting data to CSV: the export system defaults
to enclosing all text fields in quotes, so you only have to deal with
non-text fields.
So
1) export a query rather than a table
2) use calculated fields in the query to convert numeric and date/time
values into text, e.g.
fMyNumber: Format([MyNumber], "0.000")
fMyDate: Format([MyDate], "dd/mm/yyyy")
Alternatively, concatenate the fields with double quotes:
fMyNumber: """" & [MyNumber] & """"
