Levan Kekelidze (ID: 000000475d713e03) Voted 5 ★ - Updated 10/20/2023 Really useful extension. It has quite flexible configurations, like enabling line numbers, default folding on or off, using different themes etc. Plus it has a search functionality with support of regex, so you can search inside the displayed JSON. Thank you!
