Maybe I'm missing something, but is there any way to do this?
It's awkward, but it can be done by importing the information as a playlist. Imagine your data consists of two columns in Excel: [filename] and [comment]. ([filename] is the full pathname—essential for matching the target media record.) To import this as a playlist, get it into an "MPL" (XML) format that looks like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<MPL Version="2.0" Title="My Import">
<Item>
<Field Name="Filename">[filename]</Field>
<Field Name="Comment">[comment]</Field>
</Item></MPL>
In Excel, change [filename] to
<Field Name="Filename">[filename]</Field> and [comment] to
<Field Name="Comment">[comment]</Field>, then save the file as XML. Open this XML file in a text editor, and delete all but the parts that look like this:
<Row>
<Cell><Data ss:Type="String"><Field Name=
"Filename
">[filename]
</Field
></Data></Cell><Cell><Data ss:Type="String"><Field Name=
"Comment
">[comment]
</Field
></Data></Cell></Row>
Use the search and replace function of your text editor to change <Row> tags to <Item> tags, delete the
red parts and change the
green parts back into the
", < and > they were. The result will be in correct format for the
<Item> section of the MPL file. Import the resulting MPL file, and you're done.
Yes, an Excel import tool
would be nice—although it would take all the fun out of this.
