JSONOVA - JSON & XML Formatter

⚡️ JSONOVA ⚡️ is a free Chrome extension for anyone who works with JSON every day and wants a faster, cleaner way to inspect structured data directly in the browser. Open a JSON or XML response and JSONOVA turns it into a readable, interactive workspace with fast navigation, folding controls, global search, and a polished interface designed for heavy API workflows. 🔥NEW IN 1.2.0: XML SUPPORT 🔥 Open XML responses from the web or local `.xml` files. JSONOVA provides XML syntax highlighting, folding, global search, and formatted/raw views while preserving namespaces, comments, CDATA, mixed content, and nested elements. 😍 Why JSONOVA 😍 1️⃣ Very fast with large JSON and XML files Use the same focused interface for API responses, structured documents, and local files. JSONOVA activates only after confirming that the current page contains valid JSON or XML. 2️⃣ Works with local JSON and XML files Open `file://` JSON and XML files directly in Chrome and inspect them without uploading, converting, or switching to another tool. Structure counts, fold controls, global search, and line numbers keep large or deeply nested documents easier to navigate. 3️⃣ Handles big numbers in JSON Inspect payloads containing large numeric values in a structured view alongside strings, booleans, arrays, objects, and null values. 4️⃣ Low memory usage on big files The viewer is designed to keep memory usage lean, even when the JSON file is large or deeply nested. 5️⃣ Clickable web links Optionally highlight HTTP and HTTPS links inside JSON or XML. Click a highlighted link to open it in a new window while Alt + Click and drag remains available for text selection. 6️⃣ Global search and tree navigation Find values quickly, move through nested structures, and collapse or expand branches when you need a clearer view of the data. 7️⃣ Dark, light, and system theme support Match JSONOVA to the operating-system theme or choose a fixed light or dark appearance. System mode follows theme changes immediately without reloading the page. 8️⃣ Unique CSS customization JSONOVA lets you customize the output styling with your own CSS, which makes the viewer flexible for advanced personal setups. ✨ Everyday Features - Formatted and raw JSON/XML views - Expand all and collapse all controls - Global document search - Copy to clipboard - Download raw or formatted content with a generated filename and matching file type - Source URL details for protocol, host, path, and parameters - Font, line number, wrapping, tab size, folding, and structure settings - Automatic local saving of preferences - Per-page opt-out with an `OFF` extension badge and one-click reactivation - In-page viewing without switching to a separate app 🔥 Built for Real Work JSONOVA is a practical tool for developers, QA engineers, API consumers, and anyone who repeatedly inspects structured responses during API debugging, local file analysis, and data review.
