Excel 2003 SP3

I want to check data before and after it has been migrated between 2 systems
- and prove it has survived intact - using a checksum or similar.

Each dataset could be a range of numeric fields, eg telephone numbers, or
text data eg postcodes. Ideally each column would have a checksum at the
bottom which could be compared across 2 (or more) spreadsheets.

Any help greatly appreciated.

hi, ?

- when the exact time shall it be for both moments ? (put & verify a checksum)
- which column/s you need to be as checksum ? (and what type it's data ?)
- the number of rows could increase/decrease between migrations ?
- *IF* any changes... what would you like to do ?

(remember... we can only "see what you tell" in your post)

regards,
hector.
