Make JSON Readable Again
Transform nested JSON into clean, queryable tables — instantly. Run SQL directly in your browser.
Core Capabilities
Three tools. One workflow.
Visual Explorer
Flatten deeply nested JSON into clean relational tables. Arrays become linked tables with preserved relationships.
SQL Playground
Full DuckDB engine in your browser via WebAssembly. JOINs, CTEs, window functions — real analytics SQL.
Total Privacy
Zero network requests for your data. Everything runs in the browser memory sandbox. Close the tab and it's gone.
Full Toolkit
Everything built in.
Data Profiler
Instant statistical overview — column types, distributions, null rates, cardinality.
Visual Join Builder
Drag-and-drop relationship diagrams. See how flattened tables connect and build joins visually.
Monaco Editor
The same editor as VS Code. Syntax highlighting, intelligent autocomplete, keyboard shortcuts.
Multi-Format Export
Export query results as XLSX spreadsheets or Apache Parquet. Charts built in for visualization.
Query History
Every query saved automatically. Pin favorites, reuse SQL snippets, never lose your work.
Flexible Input
Paste raw text, drag & drop files, or fetch from any URL. JSON, nested or flat — it handles everything.
Workflow
Three steps. That's it.
Drop your data
Paste JSON, drag a file, or enter a URL. No configuration needed.
Auto-flattened
Nested structures are mapped into clean relational tables instantly.
Query & export
Write SQL, ask AI, chart results, export as XLSX or Parquet.
