Convert a file to JL

To convert other file formats to the "Source Code or Data" file type, you need software like Julia or a similar tool.


About JL files

A .jl file is most commonly used for either Julia source code or JSON Lines data logging. Julia is a high-level programming language designed for numerical analysis and computational science. Alternatively, in the data engineering space, .jl stands for JSON Lines, where every single line of the file is a distinct, valid JSON object. This makes it ideal for streaming massive datasets. Less frequently, .jl is used as a 16-bit integer image file by ImageJ or the VXL Computer Vision library.

While .jl files are text-based, they present real-world challenges for average users. Opening a massive JSON Lines file in standard text editors will often freeze or crash the software due to memory limits. Julia source code is useless to non-programmers without the runtime environment installed. Furthermore, these files cannot be directly imported into standard spreadsheet software like Excel.

To make this data accessible, conversion is required. For data analysis, convert your JSON Lines .jl files to CSV or XLSX formats. For sharing Julia code with colleagues who do not code, converting the file to PDF or HTML preserves the text formatting. Drop your file here to analyze and convert it - free, online, and without installing software.

Convert.Guru analyzes your JL file, detects the exact format, and lets you read the text inside.

Users also converted TSX, RED, JS and YAML files.


FAQ

If you want to convert JL file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Julia or similar software from the "Source Code & Data Logging" 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 JL, try Julia or another comparable tool in the "Source Code & Data Logging" category.



The JL 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 JL converter.
