Jira Template Filler is a Chrome extension developed by Matt Carter. This free tool is categorized under Browsers, specifically within Add-ons & Tools. The main functionality of this extension is to automatically populate the Description field in Jira with a pre-made HTML template. It is important to note that this extension works exclusively on "next-gen" projects and is designed to function only in the full-screen ticket edit view, not in the Create issue markdown editor.

Users have the option to provide their own HTML template through the toolbar menu by clicking on the designated icon. Jira Template Filler aims to streamline the process of filling out Jira issues by automating the inclusion of predefined HTML content in the Description field.
