Extract text from Qarbon files (VIEWLET)
To convert VIEWLET files to another format, you need ViewletBuilder or other Video software.
To convert other file formats to the "Screencast Project File" file type, you need software like ViewletBuilder or a similar tool.
A .viewlet file is a proprietary project file used by Qarbon ViewletBuilder to create interactive e-learning modules, software simulations, and screencasts. It stores timeline data, cursor movements, audio tracks, and raster images as a single authoring package.
You must use the original ViewletBuilder software to open, edit, and publish these files. As Wikipedia notes, screencasting tools often rely on proprietary containers to preserve interactive elements like quizzes and clickable hotspots before the final publication process.
Users frequently need to convert .viewlet files because the format is entirely closed and restrictive. You cannot play a .viewlet file in standard media players like VLC or upload it to common video hosting platforms. Opening the file requires access to ViewletBuilder, making collaboration difficult if your team does not own the correct software licenses. If you only have the project file but lack the software, your data is practically locked away.
The most practical conversion targets are standard video formats like MP4 or web-ready packages like .HTML5. Exporting to MP4 guarantees universal playback on any device, but you will permanently lose all interactive elements such as clickable buttons and text input fields. Exporting to .HTML5 preserves this interactivity for modern web browsers.
This file format is difficult to open or convert using third-party tools. It is a closed, proprietary format, and standard online converters fail because they lack the specific decoders needed to read Qarbon's timeline structure. Often, only the original software can properly read or export the data. We can inspect the file and show text or internal content. If our analysis detects a supported underlying or embedded format - such as standard images or audio files bundled inside - viewing or extraction may still be possible.
Convert.Guru analyzes your VIEWLET 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 VIEWLET converter.
