[Kmymoney] Choosing the bank import file

[huw]

Hello all

My bank's website offers a range of files for me to import transaction
data into KMyMoney.  I've been using OFX but I've noticed that the data
associated with transactions can be truncated if there's a long
"message".  Is there a better type of file I should be using, and if so,
would it cause any issues with my ledger if I suddenly switched?  My
choices are:

"Spreadsheet"
Microsoft Money 1998, 99, 00, 01, 02
Sage Line 50
Quickbooks 2005

Many thanks in advance for any advice.

Kind regards,
Huw
