About WAT files
A .wat file is primarily the WebAssembly Text Format, a human-readable S-expression representation of a WebAssembly (Wasm) binary. While excellent for debugging low-level code or understanding compiler output, .wat files are not designed for direct execution in web browsers. They are significantly larger than their binary counterparts and require compilation before deployment. Developers often find themselves stuck with a verbose .wat file when they actually need a compact, executable wasm file to integrate into a web application using JavaScript. Additionally, in the semiconductor industry, a .wat file may contain Wafer Acceptance Test data - raw parametric test results from manufacturing. These files are typically proprietary ASCII or binary logs that are incompatible with standard office software, making analysis difficult without expensive yield management systems. For WebAssembly usage, the standard workflow is converting .wat to wasm (Binary) for performance or to c/js for reverse engineering. For semiconductor data, engineers frequently need to convert these logs to csv or xlsx to visualize yield trends in Microsoft Excel.
Convert.Guru analyzes your WAT file, detects the exact format, and lets you read the text inside.

The WAT Converter Story
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 WAT converter.
