Full Toolkit

Everything built in.

Data Profiler

Instant statistical overview — column types, distributions, null rates, cardinality. Know your data before you query it.

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.

01

Drop your data

Paste JSON, drag a file, or enter a URL. No configuration needed.

02

Auto-flattened

Nested structures are mapped into clean relational tables instantly.

03

Query & export

Write SQL, ask AI, chart results, export as XLSX or Parquet.

Audience

Built for people who build things.

Backend Engineers

Debug API responses, inspect nested payloads, and trace data flows — without throwaway scripts.

Data Engineers

Profile, flatten, and query raw JSON pipelines with full SQL — right in the browser.

Data Analysts

Run SQL on JSON datasets. No database setup, no Python. Just answers.

QA Engineers

Validate complex payloads, spot schema edge cases, cross-reference structures.

Product Managers

Turn JSON exports into readable tables and charts. No engineering help needed.
