Get shape by ID

• You can use a shape’s unique ShapeId to update or control that shape on a slide.

Finding the ID of a shape:

Unfortunately, PowerPoint does not display a shape’s ID in the user interface. There are two workarounds:

• Programmatically:

  • using VBA or any library capable of reading PowerPoint XML (e.g., python-pptx).

• Manually:

  • Rename the .pptx file to .zip.

  • Open the ZIP and navigate to ppt/slides/slideX.xml.

  • Inside, look for any <p:sp>, <p:pic>, or similar shape element.

  • Each shape contains a <p:cNvPr> tag, its id attribute represents the shape’s unique ID.
