Extract text from HMI project files (2B)
To convert 2B project files to another format, you need TS-TouchWin Pro or other Data software.
To convert other file formats to the "Industrial Project Archive" file type, you need software like TS-TouchWin Pro or a similar tool.
A .2B file primarily functions as an HMI (Human-Machine Interface) project file created by TS-TouchWin Pro software. Internally, these files are structured as standard ZIP archives that contain project assets, screen layouts, and configuration data used to program industrial touch panels. Alternatively, the .2B extension is sometimes associated with Microsoft Excel spreadsheets in specific legacy or proprietary export workflows, or as Level-2B scientific data products generated by the CNSA (China National Space Administration) Ground Application System for satellite telemetry.
Users often need to convert or extract .2B files because they are proprietary and cannot be opened natively by standard operating systems without the original software installed. The main disadvantage of this format is its closed nature. Collaboration or review is impossible unless the recipient also uses the specific industrial software. Furthermore, sharing these files can trigger security warnings due to their obscure extension.
For target formats, the best approach is extracting the internal ZIP contents to access raw XML, images, or configuration texts. If the file is a spreadsheet variant, converting it to XLSX or CSV ensures broad compatibility. Standard online converters often fail to process .2B files because they lack the specific handlers for TouchWin project structures or CNSA scientific datasets. Because this file format is highly specialized, often only the original software can properly read or export the data. However, convert.guru can still identify the file format, inspect the file, and show text or internal content. If our analysis detects the supported underlying ZIP embedded format, viewing or extracting the assets may still be possible. Just drag and drop your file to identify the format, view it, and convert it when possible.
Convert.Guru analyzes your 2B file, detects the exact format, and lets you read the text inside.
Users also converted PNG, PXL, XLX and XL files.
If you want to convert 2B file to [% faq_exts_to %], you can use TS-TouchWin Pro or similar software from the "HMI Project Data Storage" category. In the File menu, look for Save As… or Export….
To convert [% faq_exts_from %] files to 2B, try TS-TouchWin Pro or another comparable tool in the "HMI Project 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 2B converter.
