Convert ALI to another file type
To convert ALI Alignments to another format, you need MODELLER or other Data software.
Convert a file to ALI
To convert other file formats to the "Sequence & Spool Data" file type, you need software like MODELLER or a similar tool.
About ALI files
A .ALI file primarily functions in two completely unrelated ways: as a Protein Sequence Alignment file for MODELLER and 3D-JIGSAW bioinformatics software, or as an ABAP List Output generated by SAP ERP. Less commonly, it acts as an index file for Microsoft Dynamics AX or an Alias file for Adobe RoboHelp.
The main disadvantage of the .ALI format is its extreme context dependency. Without knowing the source system, users cannot easily parse the data. In bioinformatics, it acts as a modified PIR format that is not always accepted by standard genome viewers. In the SAP ecosystem, it represents raw print spool data that lacks modern formatting, making it difficult to share with non-SAP users or open on mobile devices.
For bioinformatics data, converting .ALI to FASTA or TXT makes it compatible with generic sequence analysis tools. For SAP ABAP outputs, converting to CSV, XLSX, or PDF is essential for business reporting and readable sharing. Be aware that converting SAP spools outside the native environment may drop specific print formatting tags.
Because .ALI is often a closed or system-specific format, standard online converters fail to process it correctly. Just drag and drop your file to convert.guru to identify the format, view its text or internal content, and convert it when possible. If our analysis detects a supported underlying or embedded text format, viewing or conversion may still be possible.
Convert.Guru analyzes your ALI file, detects the exact format, and lets you read the text inside.
If you want to convert ALI file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use MODELLER or similar software from the "Bioinformatics Data & SAP Output" 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 ALI, try MODELLER or another comparable tool in the "Bioinformatics Data & SAP Output" category.
The ALI Converter Story
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 ALI converter.
