Excel doesn’t open CSV files correctly from sp_send_dbmail

A nice little nugget today for anyone who uses SQL dbmail to send data in csv attachments.

Sometimes, depending on your language settings, CSV files don’t open correctly in Excel. Excel ignores the ‘,’ and puts all data in column A. You then have to go through the hassle of closing the file and opening it throug the flat file wizard.

There’s a very nice solution to this that I found in this thread. It’s to insert a new row in the top of the file containing “sep=,”. This forces Excel to understand that it is a comma delimited file, and ensures that it will open correctly.

The only problem, how do you insert a header line when using dbmail?…

[Caution – ugly hack alert…]

You can alter the name of the first column to include this header text. We simply rename “Column1” to “sep=,{CR}{LF}Column1”. Then when dbmail prints out the column headers in the file, the Column1 name will be split on two lines, preceeded by “sep=,”.

Excel treats this first row as an instruction and does not display it, just uses it to make sure it formats the data correctly.

So how do we do this in SQL?

DECLARE @Column1Name VARCHAR(255)
DECLARE @Query VARCHAR(2048)
SET @Column1Name = '[sep=,' + CHAR(13) + CHAR(10) + 'Column1]'
SET @Query = 'SELECT Column1 AS ' + @Column1Name + ', Column2, Column3 FROM myTable'

EXEC msdb.dbo.sp_send_dbmail
@profile_name=XXX
,[Other parameters as required]
,@query=@Query
,@attach_query_result_as_file=1
,@query_attachment_filename='QueryResults.csv'
,@query_result_separator=',' --enforce csv
,@query_result_no_padding=1 --trim
,@query_result_width=32767  --stop wordwrap

And there you go. It’s a bit of a hack, but works well.
