## Overview
Explore, query, inspect, and export SQLite databases directly inside your browser using SQLite compiled to WebAssembly (sql.js). Filter tables, execute custom queries, view schema DDL, and download modified databases with complete data privacy.

## Format Specifications
- **Category:** Data & Config
- **Supported Formats:** `SQLite`, `DB`, `SQL`, `CSV`, `JSON`
- **Privacy Guarantee:** 0 bytes uploaded to remote servers. All computation executes locally in browser memory.
- **Compliance:** GDPR, HIPAA & SOC 2 Friendly (process sensitive payloads and PII directly on your local device).

## Technology Stack
- sql.js (WebAssembly SQLite Engine)
- Virtual Memory VFS
- Interactive Paginated Grid
- CSV / JSON Exporter

## How It Works
1. Database binaries are loaded into WebAssembly linear memory using typed Uint8Array buffers.
2. The full SQLite C-engine executes real ANSI SQL queries against the in-memory database instance.
3. Schema metadata, foreign keys, and indexes are retrieved via PRAGMA statements and sqlite_master.
4. Changes can be exported back as binary .sqlite/.db files or tabular CSV/JSON datasets.

## Practical Use Cases
### Confidential Application Database Inspection
Examine production SQLite databases from iOS, Android, Electron, or browser storage without risking proprietary customer records on cloud database SaaS tools.

### SQL Education & Query Prototyping
Practice complex SQL joins, aggregations, window functions, and subqueries with instant latency-free feedback.

### Data Cleansing & Extraction
Run SELECT and UPDATE queries on raw SQLite tables and export clean filtered datasets as CSV or JSON.

### Offline Desktop & Mobile App Testing
Inspect local caching databases from test builds and generate test datasets completely disconnected from the network.

## Frequently Asked Questions
### Is my SQLite database uploaded to any remote server?
No. The SQLite engine is compiled directly into WebAssembly and runs in your browser tab. Your database file is read into local browser RAM only.

### Can I run destructive queries like DROP, UPDATE, and DELETE?
Yes. You have full administrative control over the in-memory database instance. You can run any valid SQLite statement and export the updated database file when finished.

### What happens when I close the browser tab?
Because everything is kept strictly in volatile browser memory for maximum privacy, all in-memory data is purged immediately when you close or reload the tab. Make sure to download your database if you made modifications.
