i'm trying to import an excel worksheet into an access table, i've set everything ok, i've done this before a thousand times, but now an unknown error pops up in the last step, it just says "error trying to import the file <url>, file not imported"

this is very strange, it had never happened before, i don't know if it's some problem with the excel file or with the data

when i chose 'first row contains column headers' an error pops up saying that the first row contains some data that can't be a header, but that error has happened lots of times before without bad consequences

do you have an idea of what could be wrong?? the error doesn't have any useful info so i'm lost with this

thanks for your advise
