Extract text from Game data and quarantined files (ZLX)
To convert ZLX Data files to another format, you need Elden Ring or other Game software.
To convert other file formats to the "Proprietary Game Data" file type, you need software like Elden Ring or a similar tool.
The .ZLX file is a proprietary game data format used heavily in the action role-playing game Elden Ring. It primarily functions as a storage container for loot drop tables, item parameters, and internal game logic. Because it is a proprietary binary format, standard software cannot open it. Modders rely on specialized, community-built tools like DSMapStudio or WitchyBND to unpack and read the contents.
The main disadvantage of the .ZLX format is its closed ecosystem. Files are compressed, sometimes encrypted, and lack a public specification. Opening a .ZLX file in a standard text editor yields unreadable gibberish. Modifying these files incorrectly will corrupt your game save or cause immediate crashes. Additionally, altering them while playing online will trigger Easy Anti-Cheat (EAC) bans.
Users typically need to convert .ZLX to human-readable formats like XML or JSON to edit loot tables safely. After editing, the data must be repacked into the original .ZLX structure. Standard online converters fail to process it because they cannot decode FromSoftware's proprietary engine parameters. Just drag and drop your file to identify the format, view it, and convert it when possible. convert.guru can still identify the file format, inspect the file, and show text or internal hex content. If our analysis detects a supported underlying or embedded text format, viewing or conversion may still be possible.
Convert.Guru analyzes your ZLX file, detects the exact format, and lets you read the text inside.
Users also converted SL2, XBIN and AZX files.
If you want to convert ZLX file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Elden Ring or similar software from the "Elden Ring Game Data" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to ZLX, try Elden Ring or another comparable tool in the "Elden Ring Game Data" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ZLX converter.
