Jira YAML Viewer is a free Chrome extension designed to enhance the Jira experience by allowing users to visualize compressed YAML data directly within Jira cards. When a card containing YAML code is opened, the extension provides an interactive popup that displays the YAML data in a well-formatted table. This functionality is particularly useful for developers and engineers working with infrastructure as code, enabling them to quickly interpret YAML files stored in Jira descriptions.

The extension utilizes the pako library for decompressing gzip/base64 content, converts YAML to JSON using the yaml library, and renders the data in an interactive table using Tabulator. Users can easily sort, filter, and export the displayed data to CSV or Excel format with a single click. This non-intrusive tool does not alter Jira's structure or collect user data, ensuring a seamless and secure experience.
