SQL & Parquet Data Analyzer
Data & analysis Local only
SQLite Database Viewer & Editor
Local SQLite WebAssemblyOpen, query, edit, validate and export SQLite databases locally with schema and integrity diagnostics.
Open a SQLite database locally
Browse schema and rows, run SQL, inspect query plans, check integrity and export a modified copy without uploading the database.
Database bytes stay in this browser
SQLite WebAssembly is loaded only after you open a database or example. This session is in-memory and nothing is sent to a server.
How to use it
- 01
Open a SQLite database
Choose a bounded SQLite file or load the generated example; the database is opened by a lazy local WebAssembly runtime.
- 02
Explore and query
Browse tables, columns, foreign keys, views, indexes and triggers, then run SQL or inspect query plans without sending values away.
- 03
Check, edit and export
Run integrity and foreign-key checks, explicitly enable edits, and export a modified database or redacted review evidence.
Frequently asked questions
How is this different from SQL & Parquet Data Analyzer?
SQL & Parquet Data Analyzer uses DuckDB for CSV, JSON and Parquet analytics. SQLite Database Viewer & Editor preserves and edits actual SQLite database files, schema objects and SQLite-specific diagnostics.
Is my database uploaded?
No. SQLite WebAssembly opens database bytes in this browser tab. Exports are generated locally and there is no database or API server.
Does integrity_check guarantee the data is correct?
No. It checks important structural invariants. Application semantics, encryption, WAL recovery and every form of corruption still require appropriate native tools and backups.
Can it open SQLCipher databases?
No. Encrypted SQLite variants require their encryption extension and keys; this static tool deliberately does not request or transmit them.
