YAML to JSON Converter

WHAT IT DOES

YAML to JSON Converter transforms YAML (YAML Ain't Markup Language) data into JSON format. YAML is commonly used for configuration files, and this tool makes it easy to convert them to JSON for use in JavaScript applications, APIs, and data processing. Paste your YAML or upload a .yaml or .yml file, and the tool generates clean JSON output. You can customize the output with options including pretty or compact formatting, key sorting, type preservation, key quoting, and null representation. A preview shows the resulting JSON, and you can copy it to your clipboard or download it as a .json file.

WHERE IT RUNS

The extension runs entirely within your browser's local environment using the BotGentz framework. All YAML parsing, JSON generation, and data processing occur on your machine without any network requests. No YAML data, JSON 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 a custom YAML parser implemented in pure JavaScript.

HOW TO USE

Click the extension toolbar icon to open the YAML to JSON Converter panel. Paste YAML data into the input area or click the file input to upload a .yaml or .yml file. Click "Convert" to generate the JSON output. The preview shows the converted JSON with a clean, formatted display. Click "Copy JSON" to copy the output to your clipboard. Click "Download JSON" to save the output as a .json file. Toggle "Sort keys" to alphabetically sort object keys in the output. Toggle "Preserve types" to maintain data types (numbers, booleans, null) during conversion. Toggle "Quote keys" to wrap object keys in quotes. Select the "Output Format" (Pretty or Compact) to control the JSON formatting. The tool updates automatically when you change settings.

THE YAML TO JSON ENGINE — WHY IT WORKS

Most YAML to JSON converters rely on third-party libraries or external services. This tool uses a custom recursive parser that handles basic YAML syntax including key-value pairs, nested objects, arrays, and primitive values. The parser processes YAML line by line, tracking indentation levels to build a nested object structure. It handles comments (lines starting with #) by ignoring them, and supports inline arrays and objects. The type preservation system automatically detects and converts numbers, booleans, and null values. The sort keys option uses JavaScript's sort method to order object keys alphabetically before serialization. The quote keys option ensures all keys are quoted in the JSON output (valid JSON requires quoted keys). The pretty/compact formatting uses JSON.stringify with or without indentation. This approach provides a lightweight, self-contained YAML-to-JSON conversion without any external dependencies.

THE PANEL

The YAML to JSON 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 YAML in multiple tabs simultaneously.

PLEASE NOTE

This extension requires the free BotGentz extension framework to be installed and enabled. The tool supports basic YAML syntax and may not handle all YAML 1.2 specification features (e.g., anchors, aliases, multi-line strings with complex formatting). The parser is designed for common YAML configurations used in development. Comments are preserved in the parsing process but are not included in the JSON output. Large YAML files may take a moment to process. 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.
