JSON Tree Inspector is an offline desktop workbench for inspecting large JSON and newline-delimited JSONL files, formatting or minifying payloads, comparing structural tree differences, and flattening nested records into tabular exports.

Key Features:

• JSON & JSONL Tree Explorer: Parse standard JSON documents and .jsonl streams into a lazy-loaded hierarchy with color-coded type badges (str, num, bool, null, array, object), one-click JSONPath copying (e.g. $.users[0].name), and path/key/value filtering including wildcard queries like $.items[*].price.
• Formatter & Structural JSON Diff: Switch between 2-space or 4-space pretty printing (with optional sorted keys) and compact minified output, plus run side-by-side structural comparisons highlighting Added, Removed, Type-Changed, and Modified paths.
• Flatten & Table Exporter: Flatten nested objects and arrays with dot notation into CSV, TSV, Markdown Table, and .jsonl files with live preview.
