I want to modify the description and name of a number of components in schematic library.
How can I do that effectively?
Right now, I have to do it manually which is not really nice to do because I have thousands of components.
For example, I want to delete the description of these components: enter image description here

Thanks in advance.

  • \$\begingroup\$ You will either have to do this by hand or by script, I'm fairly sure this is doable by script \$\endgroup\$

  • \$\begingroup\$ You can copy-paste the contents to an Excel spreadsheet. Either work in Excel or convert the Excel format to plain text to edit. In the future, consider using an Excel include file (Tools -> Update Parameters From Database) as it is more efficient for single users. \$\endgroup\$

1 Answer 1


Option 1: The SCHLIB List panel is probably a good place to start. See the official documentation here: https://www.altium.com/documentation/altium-designer/sch-pnl-schliblistschlib-list-ad

Open a SchLib file, then open the SCHLIB List panel and select Edit all objects from all components include only Parts at the top of the SCHLIB panel:

enter image description here

That should get you started, and allow you to edit the descriptions like a spreadsheet.

Option 2: The Parameter Manager tool is another way to do this. Again the official documentation is here: https://www.altium.com/documentation/altium-designer/workspacemanager-dlg-parametereditorformparameter-table-editor-ad

With a Schlib open navigate the menus to Tools -> Parameter Manager.... In the Parameter Editor Options Panel, check only Parts in Include Parameters Owned by section. Make sure Exclude System Parameters is not checked (i.e. you want to include system parameters) in the Other Options section:

enter image description here

Press OK and you should be able to modify the 'Description' under the System Parameters sub-column. Then be sure to Apply Changes and complete the ECO process...
