Extract text from TI-73 data lists (73L)
To convert 73L data lists to another format, you need TI Connect or other Data software.
To convert other file formats to the "Calculator List File" file type, you need software like TI Connect or a similar tool.
A .73L file contains list data generated by the Texas Instruments TI-73 Explorer graphing calculator. These lists typically store numeric sets, coordinates, or basic text strings used for mathematics and statistics exercises. Users manage these files on a computer via the TI Connect software, which transfers the data via a link cable.
The main disadvantage of the .73L format is its proprietary, binary encoding. It is unreadable by standard computer programs, making it impossible to share data sets directly with modern tools like Microsoft Excel or Google Sheets. Users must convert this file to access the raw values.
The most practical conversion targets are CSV and TXT. Converting to these formats allows the math or statistics data to be parsed by almost any spreadsheet application or script, though specific calculator formatting may be lost.
Because this is a closed, proprietary format heavily tied to legacy hardware, standard online converters often fail to process it. If our analysis detects extractable numerical data, viewing or conversion may still be possible.
Convert.Guru analyzes your 73L file, detects the exact format, and lets you read the text inside.
Users also converted 73G, 73I and 73K files.
If you want to convert 73L file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use TI Connect or similar software from the "Calculator Data Storage" 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 73L, try TI Connect or another comparable tool in the "Calculator Data Storage" 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 73L converter.
