Extract text from Shell scripts (FISH)
To convert FISH scripts to another format, you need The Fish Shell or other Developer software.
To convert other file formats to the "Shell Script File" file type, you need software like The Fish Shell or a similar tool.
A .fish file represents several distinct data types, but it is predominantly known as a Fish shell script file used by The Fish Shell, a popular Unix-like command-line interface. These files contain plain text scripts built to automate tasks, set environment variables, and manage system configurations. Alternatively, a .fish file may be a Framer design prototype project, which relies on a hidden ZIP container format to store assets. Less commonly, it functions as proprietary game data for the game Sudeki or as compressed audio generated by FMOD Studio.
Users typically need to convert .fish files because they suffer from strict environment dependency. A Fish shell script is useless on a native Windows machine without complex workarounds, and its syntax is completely incompatible with standard Bash scripts. Similarly, Framer design files and game data archives are closed, proprietary formats that lock your assets behind specific software. You cannot simply share these files with colleagues who do not own the original software. Standard online converters fail with these files because they cannot parse the unique scripting syntax or decode the proprietary game engine compression.
If you have a script, the best target formats are TXT for reading or SH for execution (though manual syntax translation to Bash is required). If you are dealing with a Framer project, you want to extract the internal PNG images and JSON data.
Because many .fish files use undocumented or proprietary structures, standard conversion is difficult. Often, only the original software can properly read or export the data. Just drag and drop your file into convert.guru to identify the exact format. If our analysis detects an embedded ZIP archive or plain text script, viewing or extraction may still be possible without the original software.
Convert.Guru analyzes your FISH file, detects the exact format, and lets you read the text inside.
Users also converted HSP, KS, GSE and BASH files.
If you want to convert FISH file to BASH, you can use The Fish Shell or similar software from the "Shell Script & Prototype Storage" category. In the File menu, look for Save As… or Export….
To convert files to FISH, try The Fish Shell or another comparable tool in the "Shell Script & Prototype 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 FISH converter.
