"Albert Einstein" a écrit dans le message de news:
...
I imported a faxed spreadsheet into OmniPage and directed it to output the
data into an Excel spreadsheet.

It did a good job, except that the dates in the date column were all
changed into early twentieth century dates.

Instead of adding 100 years to each date one-by-one, can I add 100 years
to the entire column with one command?
