I walk through the upgraded table extensions code editor in Tableau 2023.1, comparing it against 22.4 where pasted code received no syntax support. I show the new right-click language selection, proper syntax highlighting, a code mini map and a command palette.

## Key takeaways

- In 22.4 the table extensions editor applied no syntax highlighting to pasted code, whereas 2023.1 adds proper formatting and line numbers
- Right-clicking in the editor lets you set the language to JavaScript, plain text, Python or R for correct syntax highlighting
- A mini map on the right-hand side helps you navigate long blocks of code quickly
- A built-in command palette makes troubleshooting and fixing bugs within the editor easier
