Extract text from sequence data files (ASN)
To convert ASN data files to another format, you need NCBI BLAST or other Data software.
To convert other file formats to the "Abstract Syntax Notation File" file type, you need software like NCBI BLAST or a similar tool.
The .ASN file extension is predominantly associated with Abstract Syntax Notation One (ASN.1), an international standard for data serialization. In the scientific community, it is heavily used by the NCBI (National Center for Biotechnology Information) to store genetic sequence data, chemical substance records, and NCBI BLAST search strategies. In telecommunications and cryptography, it defines the underlying data structures for protocols and digital certificates.
Working with .ASN files is notoriously difficult outside of specialized software. The format relies on strict, often nested schemas that cannot be easily read by standard office applications. Sharing a raw .ASN file with a colleague who lacks the proper bioinformatics suite or an ASN.1 compiler typically results in an unopenable file or a screen full of confusing code. Furthermore, compiling raw ASN.1 schemas presents a steep learning curve for non-developers, and binary implementations (like those used in Thermo Scientific surface analysis) are completely opaque without proprietary viewers.
To make this data accessible, conversion is the most pragmatic solution. For database integration and web use, convert .ASN to XML or JSON, which perfectly preserves the hierarchical data structure. If you need to share biological sequence data or analyze it using spreadsheet tools, converting to CSV or FASTA is highly recommended.

Convert.Guru analyzes your ASN file, detects the exact format, and lets you read the text inside.
Users also converted ASN1, CDR, TXT, XLSX, PDF, STP, CSV, JPG, DAT, FNA, FSA_NT and IP files.
If you want to convert ASN file to IP, CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT or DB, you can use NCBI BLAST or similar software from the "Bioinformatics and Protocol Data Structure" 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 ASN, try NCBI BLAST or another comparable tool in the "Bioinformatics and Protocol Data Structure" 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 ASN converter.
