You want to export (extract) block attributes to a comma- or space-delimited text file using a custom template file but AutoCAD reports the error 'Invalid field specification'.

Make sure you are using a proper format for the template file (an ASCII file) - e.g. (for blocks with the attributes "Name" and "Height"):

BL:Name   C016000
Name      C016000
Height    N004001
There should be no additional CRLF (Enter/Newline) character at the end of the last line.

Instead of ATREXT you can also try the new EATTEXT command.
