Hi Paul,
Thx for advice.
1) we do not have manual intervention in the process when data file .TXT import to mailmerge in word now, as say, we have over hundred letters, so not prefer change in this process.
2) numeric field H96 under type 'general' will have data 1234567890123456 change to 1234567890123450 after save in excel, that is not wanted, unless handle manually.
3) Is there is a fix in the word 2007 ? As we have other letter ok in import/merge more than 1 record. Change>Repair will be tested later as this need administrator.
