Hello!
In MS Excel, in the settings window for external data connections, there is a button "Export connection file | Save", which, when clicked, automatically creates a file with the extension odc (Office Data Connection).

The odc file itself is an html structure created according to all the rules with html/meta/head/body tags, etc., which also includes inserts of xml, style and script blocks.

The xml block contains information about connection parameters - type (oledb/odbc), connection string, sql query. The style and script
blocks are not empty, but, as it turned out, their content is not used (more precisely, it is not used, not called ) when importing data. It's a pity! - it could turn out to be a good, strong functionality, if by means of javascript it was possible to somehow influence the array (stream) of imported data. Dear colleagues, what do you think, what purpose of the script block was laid down by the developers of MS Office, why does it not affect the order of displaying (outputting) data, and is it possible to somehow use the javascript functionality? body onload
