JSON to YAML Converter

WHAT IT DOES

JSON to YAML Converter transforms JSON data into YAML (YAML Ain't Markup Language) format, a human-readable data serialization standard commonly used for configuration files. Paste your JSON or upload a JSON file, and the tool generates clean, formatted YAML output. You can customize the conversion with options including indent size (2, 4, or 8 spaces), flow style (block or inline), string quoting, key sorting, and null value representation. A preview shows the resulting YAML, and you can copy it to your clipboard or download it as a .yaml file.

WHERE IT RUNS

The extension runs entirely within your browser's local environment using the BotGentz framework. All JSON parsing, YAML generation, and data processing occur on your machine without any network requests. No JSON data, YAML output, or user activity is ever transmitted, uploaded, or stored externally. The tool works on any website and respects the browser's security boundaries, operating within the isolated extension sandbox. Data conversion uses pure JavaScript object traversal and string generation.

HOW TO USE

Click the extension toolbar icon to open the JSON to YAML Converter panel. Paste JSON data into the input area or click the file input to upload a .json file. Click "Convert" to generate the YAML output. The preview shows the converted YAML with a clean, formatted display. Click "Copy YAML" to copy the output to your clipboard. Click "Download YAML" to save the output as a .yaml file. Toggle "Sort keys" to alphabetically sort object keys in the output. Toggle "Quote strings" to wrap all string values in quotes. Select the "Indent Size" (2, 4, or 8 spaces) to control the indentation level. Select the "Flow Style" (Block or Flow) to control whether arrays and objects are rendered as multi-line blocks or inline. Set the "Null value" to specify how null values should be represented. The tool updates automatically when you change settings.

THE JSON TO YAML ENGINE — WHY IT WORKS

Most JSON to YAML converters use third-party libraries or external services. This tool uses a pure JavaScript recursive traversal engine that converts JSON objects to YAML syntax according to the YAML 1.2 specification. The engine recursively walks through the JSON data structure: for objects, it outputs key-value pairs with proper indentation; for arrays, it outputs list items with dashes; for primitive values, it outputs the value in YAML syntax. The engine handles strings with special characters (colons, spaces, hashes, newlines) by quoting them as needed. The indent size controls the number of spaces for each nesting level. Flow style controls whether arrays and objects are rendered in inline format (e.g., {key: value}) or block format (multi-line). The sort keys option sorts object keys alphabetically for consistent output. This approach provides full control over the YAML output format without any external dependencies.

THE PANEL

The JSON to YAML Converter panel is fully draggable by its title bar and remembers its position on screen per website. It snaps to the edges of your browser window for clean alignment. Collapse the panel to a compact icon strip using the minimize button, restoring it with a single click. Resize the panel by dragging any edge or corner; the input area, output preview, and controls adjust proportionally. Press the Escape key to close the panel instantly. The panel maintains independent state for each browser tab, allowing you to convert JSON in multiple tabs simultaneously.

PLEASE NOTE

This extension requires the free BotGentz extension framework to be installed and enabled. The tool expects valid JSON input; malformed JSON will show an error message. Large JSON datasets may take a moment to process; the preview shows the full output but the panel may scroll. The YAML output follows YAML 1.2 syntax but may not handle all edge cases of the specification. The flow style option only applies to arrays and objects; all other values are rendered in block style. All conversion data is processed locally and is never transmitted, logged, or shared. The extension requests no network permissions and functions entirely offline. The source code is fully auditable and available for review.
