Extract text from Flexcil backup files (FLEX)
To convert FLEX backups to another format, you need Flexcil or other Data software.
To convert other file formats to the "Note Archive & Source Code" file type, you need software like Flexcil or a similar tool.
The .flex file extension serves several completely different purposes depending on the software that created it. Most commonly, it functions as a note-taking document or backup archive generated by the Flexcil mobile application. Under the hood, this specific variant operates as a standard ZIP container holding user data, annotations, and embedded PDF files. Another highly common use for the .flex extension is as a source code file for lexical analyzer generators like JFlex or Flex. In these instances, the file is simply plain text containing rules that map regular expressions to C or Java code. Rarely, the extension is used as an analytics cache file for Apache Druid or Apache Impala, or as a specialized digital camera raw image (based on TIFF) by Imacon/Hasselblad FlexColor software.
Users often need to convert .flex files because the current formats are heavily restricted by their native software environments. Flexcil backups are proprietary to their mobile app ecosystem; without the app installed, you cannot natively view your notes. Lexical analyzer files require specialized command-line compilation environments, making them largely useless to non-developers.
For Flexcil users, the best workaround is to treat the file as an archive: rename the extension to ZIP to manually extract the internal PDF documents. For lexical analyzer source files, converting the file to standard TXT or compiling it to JAVA allows for easy reading in any standard text editor. Hasselblad raw images should be exported to JPG or standard TIFF to regain broad compatibility.
Because the .flex extension represents fundamentally different formats - ranging from compressed archives and plain text to raw image sensor data - generic online converters frequently fail to process it. Standard conversion tools cannot instantly determine which variant they are dealing with, and often, only the original software can properly interpret the internal data. If our analysis detects a supported underlying format like a ZIP archive or plain text, viewing or extracting the contents may still be possible.
Convert.Guru analyzes your FLEX file, detects the exact format, and lets you read the text inside.
Users also converted FLX, FS, PG, VRM, TABLE and GRID files.
If you want to convert FLEX file to TABLE or GRID, you can use Flexcil or similar software from the "Note Backup & Lexical Source" category. In the File menu, look for Save As… or Export….

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 FLEX converter.
