Extract text from Tarsia jigsaw files (FJSW)
To convert FJSW jigsaw files to another format, you need Formulator Tarsia or other Data software.
To convert other file formats to the "Tarsia Jigsaw Puzzle File" file type, you need software like Formulator Tarsia or a similar tool.
.FJSW files are proprietary puzzle documents created by Formulator Tarsia, specialized educational software developed by Hermitech Laboratory. Teachers use these files to build printable mathematical jigsaw puzzles, domino activities, and matching games. Under the hood, approximately 81% of .FJSW files are stored as plain XML, while the remaining 18% use UTF-16 (LE) text encoding.
The main disadvantage of the .FJSW format is its strict dependency on obsolete, niche software. Because it is a closed educational format, students and colleagues cannot open these files unless they install the exact Windows software. It is not natively supported by web browsers, macOS, or modern mobile devices, making sharing highly restrictive.
Users urgently need to convert .FJSW files to PDF for reliable printing and digital sharing, or to XML to extract the underlying mathematical equations. However, standard online converters fail because the exact geometric rendering engine is proprietary to Hermitech.
This file format is notoriously difficult to natively convert outside its ecosystem. Often, only the original Formulator Tarsia software can properly read or export the graphical jigsaw layouts. Since our analysis detects the supported underlying XML and UTF-16 data, viewing the raw text expressions and recovering your puzzle data is still highly possible without the original program.
Convert.Guru analyzes your FJSW file, detects the exact format, and lets you read the text inside.

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 FJSW converter.
