Word has a number of different methods of connecting to mail merge data sources, including DDE and OLE DB. Word 2002 and later use the OLE DB coonection by default, though you can change this (to DDE, for example). To work around a limitation in the OLE DB provider used to get data from Excel etc., when Word is connected to an OLE DB data source, it treats dates as if they are in the US mm/dd/yy format, regardless of the format in Excel, your regional settings etc. Applying a date format switch fixes that - and gives the mailmerge document the ability to format the date independently of whatever format is used in the data source.

To get the date format you want, you can add a formatting picture switch as follows:

• select the mergefield;

• press Shift-F9 to expose the field coding. It should look something like {MERGEFIELD MyDate} where 'MyDate' is your mergefield's name;

• delete anything appearing after the mergefield's name and add '@ "dd-MMM-yy"' to the field, as in {MERGEFIELD MyDate @ "d MMMM yyyy"}. With this switch your date will come out as '2 August 2008'. Other possible date formatting switches include:

. @ "dddd, d MMMM yyyy";

. @ "ddd, d MMMM yyyy";

. @ "d MMM yyyy";

. @ "dd/MMM/yyyy".

Note: Note: you can swap the d, M, y expressions around, but you must use uppercase 'M's for months - lowercase 'm's are for minutes.

• position the cursor anywhere in this field and press F9 to update it;

• run your mailmerge.

    You probably still have the dates in a mix of d/m/y & m/d/y formats in Excel - you need to ensure they're all the same. If you format all the cells in Excel as d-mmm-yyyy, for example, you'll probably find that some are not what they presently look like.

    Your description suggests the regional settings of the two PCs differ regarding the date format - you need to check both the short dates and the long dates.

    Hi, thanks for your reply.

    I checked the machine that works OK and changed the date formats in the control panel to match. The codes are the same now but I still get 10-nov-17 where it should be 11-oct-17. If i keep it to preserve fomratting during updates the format changes but it appears correct. Its only when i add the switch to make the month appear in word format rather than number.

    Any other ideas. My region settings look like this... the switch code is the same : MERGEFIELD APP_Date @"dd-MMM-yy"

    Your description suggests your PC's regional settings are configured for a M-D-Y date format, in which case you need to either: a) ensure the dates are input into Excel in that format; or b) reconfigure your PC's regional settings are configured for a D_M-Y date format.

    I've formatted as d/M/yy in a mail merge from Excel into Word which works fine for double digit dates ie 12th December - 12/12/18 but 1st March and 2nd June are showing as 3/1/18 and 6/2/18

    About to pull out a large clump of hair!!  Any ideas, please?
