These LISP commands -- AttRead and AttWrite -- are attribute import and export utilities.

The LISP commands -- AttRead and AttWrite -- are attribute import and export utilities. AttWrite will create a comma-delimited file (CSV) that can be read and processed by Excel. The data extracted is for a single block instance. When it runs, you will be asked to pick the border or block for the extract. A CSV file is created that contains each attribute tag and value in a line. AttRead is the opposite. Select the block, and the tag/value file is read and the attribute values are changed based on the tag names. This simple routine is a great example of how you can pass data from drawings to other applications and get back other data.
