# Replacing tags

To update the tags in your slides, provide a list of key-value pairs for each slide. PowerPoint Generator API will then find and replace all matching tags with the specified values.

To create a tag, enclose your text in double curly braces, like this: `{{example_tag}}`.

Tags can be placed in text boxes or table shapes, making it easy to customize your presentation dynamically.
