Clay has a text search function that allows you to find cells matching specific criteria in your table, but there isn't a dedicated search and replace function mentioned in the documentation.
To search for text:
1. Click the Search Bar at the top of your table
2. Enter your search criteria and press Search
3. Use the navigation arrows to move between matches
You can search within cell outputs using the Cell Details panel, but replacing text across multiple cells isn't mentioned as a built-in feature.
