SQLite Manager enables you to open, browse, and edit standalone SQLite databases without installing desktop software. Simply introduce a .db or .sqlite file and the interface reveals every table, view, index, and trigger in a tidy, searchable catalogue. Professionals gain immediate insight into data structures, while hobbyists enjoy an approachable pathway to query construction and result exploration.

Behind the streamlined façade lies a robust execution engine that parses schemas, formats SQL, and returns result sets in milliseconds. Inline editing, batch commits, and contextual validation protect data integrity during interactive sessions. Export options allow friction-free extraction of query outputs to CSV, facilitating downstream analytics or archival workflows in any environment.

Designed for privacy-sensitive, air-gapped, or on-the-go scenarios, SQLite Manager runs entirely client-side, ensuring uploaded databases never leave your device. Its responsive Bootstrap 5 layout, accessible controls, and keyboard-centric shortcuts maximise productivity across laptops, tablets, and high-resolution desktops alike—ideal for rapid troubleshooting, educational demonstrations, or full-scale dataset inspections.

Sample Query

SELECT customer_id,
       SUM(total) AS lifetime_value
FROM   orders
WHERE  order_date >= DATE('now','-1 year')
GROUP  BY customer_id
ORDER  BY lifetime_value DESC
LIMIT  100;

Step-by-Step Guide

Follow these precise steps to inspect and modify a database efficiently.

  1. Click or drop a .db/.sqlite file onto the Drop Zone.
  2. Watch the sidebar populate with objects; use the search input to narrow results.
  3. Select a table and press Enter to load the default SELECT * query.
  4. Edit the SQL text area to refine columns or add WHERE clauses, then click Run.
  5. Activate Edit rows to make inline changes Tip.
  6. Press Save to commit edits or Cancel to roll back Caution.
  7. Export results by choosing CSV; filenames inherit the active object.

FAQ

Commonly asked questions and concise answers follow.

Does the tool upload my database to a server?

No. All processing occurs locally in your browser; the file never leaves your machine.

Can I connect to a remote SQLite database?

Export the remote file first, then open it here. Direct network connections are not supported.

How large a database can it handle?

Performance remains smooth with files up to several hundred megabytes, depending on device memory.

Does editing affect foreign-key constraints?

Yes. The underlying engine respects existing constraints; invalid updates trigger descriptive errors.

Where is my query history stored?

Histories persist in browser localStorage and can be cleared through the interface at any time.

Troubleshooting

If difficulties arise, consult the resolutions below before seeking further assistance.

  • Database fails to load — Ensure the file has a valid SQLite header and is not password-protected.
  • No tables displayed — The database may contain only internal system objects; verify with another viewer.
  • “Malformed query” error — Click Format to reveal syntax issues, then revise accordingly.
  • Edits do not persist — Confirm Save was clicked and that triggers are not rolling back transactions.
  • CSV download is empty — Run the query again to populate the result grid before exporting.

Advanced Tips

Leverage the following practices to maximise efficiency.

  • Prefix complex queries with EXPLAIN QUERY PLAN to analyse performance.
  • Use temporary tables for iterative transformations before committing changes.
  • Assign aliases to lengthy column names to improve readability in result tables.
  • Chain multiple statements with semicolons; history records them as a single entry.
  • Combine .mode csv style exports with spreadsheet pivot tables for rapid reporting.

Glossary
