What People Use It For

Something wrote a LevelDB, and you have to read it

An embedded store, a profile, a cache - opened directly as a tree of keys, with values shown as text, JSON, HEX or image, depending on the bytes.

One entry is wrong

A setting holds an old value, a key is corrupt, an application will not start. Change it, add a key, delete one - no program written just for the correction.

Getting the contents out of the binary

The whole database or a range of keys, out to JSON, CSV, TSV, Excel, XML, SQL or TXT - for a backup, a diff, or a report somebody can read.

A whole set of keys to load

Seed a development store or restore an export from JSON, CSV or XML, without writing a bulk-load program for every store.

An empty store, and something to put in it

Create a LevelDB for a library or a test, fill it from a screen, and keep the seed data as a reviewable file in the repository.

The basic operations: open / create LevelDB, edit a LevelDB key, export keys to files, import keys from files.

Who Uses It

Six roles, one problem: something wrote a LevelDB, and it has to be read

Backend and app developers

Check a key, fix one value, or seed test data in an embedded store - without writing a program for it.

Electron and Chromium users

See what Chrome, Edge and Electron store on disk: Local Storage grouped by site, IndexedDB as a tree.

Digital forensics and IR

Read a running store without taking the lock, and unwrap encoded values layer by layer.

Game modding

Open the LevelDB behind a save - world, inventory and player data - as JSON, HEX or an image.

Data recovery and troubleshooting

When a store will not open, detect the comparer, open a copy, and export what can still be read.

Test data and seeding

Keep seed data as a reviewable CSV, JSON, XML or TXT file and load it into a store in one import.

Frequently Asked Questions

Answers to common questions about Level Data Studio

What versions of LevelDB does Level Data Studio support? +

Level Data Studio supports all major versions of LevelDB including 1.18, 1.20, 1.21, 1.22 and the latest 1.23. The tool is backward compatible with older LevelDB databases and can handle both legacy and modern LevelDB file formats.

Does Level Data Studio require an internet connection? +

No, Level Data Studio is a fully offline application. All LevelDB processing happens locally on your computer - no data is ever uploaded to our servers or any cloud service. The only time you need internet is when downloading the installer (optional, as you can transfer it via USB).

Can I edit large LevelDB databases with Level Data Studio? +

Yes! Level Data Studio is optimized for large LevelDB databases and can handle files up to 10GB in size with millions of key-value pairs. We use memory-efficient processing and incremental loading to ensure smooth performance even with very large LevelDB files.

What export formats are supported? +

Level Data Studio supports exporting LevelDB data to JSON (including pretty print), CSV (comma-separated values), XML, TXT (plain text). You can export the entire database or just selected key-value pairs, with customizable formatting options for each format.

Is it safe to edit LevelDB databases with this tool? +

Yes, Level Data Studio includes multiple safety features to prevent data loss: automatic backups before editing, undo/redo functionality for all operations, transactional editing, and error recovery mechanisms. We recommend creating a backup before making major changes to critical LevelDB databases.

Do I have to write a program to read a LevelDB database? +

No. An assistant can write you one, but the part that remains is opening the actual store: LevelDB keeps an exclusive lock, so the application that owns it has to be closed first, and the values are raw bytes that have to be shown as text, JSON, HEX or an image. Level Data Studio opens the files directly - look, fix a key or export - with nothing to maintain and nothing uploaded.
