Extract text from Unity asset files (BLOCK)
To convert BLOCK asset files to another format, you need Unity or other Data software.
To convert other file formats to the "Game Asset & Ledger" file type, you need software like Unity or a similar tool.
The .BLOCK file extension is highly overloaded, meaning it is used by several completely different, mutually incompatible systems. The most widespread use case is as an encrypted asset cache or UnityFS bundle within the Unity game engine. In this context, the file packs 3D models, textures, and audio into a single proprietary blob. Other common uses include immutable ledger files in Hyperledger Fabric, UTF-8 encoded visual coding projects in platforms like Tynker or Scratch, JSON-formatted guitar presets for Headrush pedalboards, and binary firmware updates for satellite receivers utilizing ALI Corp or NCRC chipsets.
These formats present severe disadvantages regarding interoperability. Because most .BLOCK files are compiled, encrypted, or hardware-specific, they cannot simply be double-clicked or edited. Unity bundles are closed proprietary archives requiring reverse-engineering tools to unpack. Hyperledger blocks rely on cryptographic hashing where arbitrary conversion would destroy the network consensus. Satellite firmware consists of raw binary blobs that will "brick" hardware if tampered with.
Direct conversion to standard formats is only possible depending on the exact source type. Educational coding files and Headrush presets are often just JSON or XML text under the hood, meaning they can be easily converted or extracted to standard TXT or JSON files. For Unity caches, standard document converters are useless; you must extract the underlying media to OBJ, PNG, or WAV using dedicated unpackers like AssetStudio.
This extreme variation makes .BLOCK files inherently difficult to handle. Standard online converters fail because they lack the context to understand which "flavor" of block they are looking at. Just drag and drop your file to identify the format, view its internal structure, and convert it when possible. If our analysis detects an underlying text format, readable JSON, or an unpackable archive, convert.guru will help you access the data hidden inside.
Convert.Guru analyzes your BLOCK file, detects the exact format, and lets you read the text inside.
Users also converted MCA, MCH, LANG and GB files.
If you want to convert BLOCK file to GB, CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT or DB, you can use Unity or similar software from the "Game Asset & Data Cache" 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 BLOCK, try Unity or another comparable tool in the "Game Asset & Data Cache" 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 BLOCK converter.
