About PQA files

The .PQA file is primarily a Power Quality Analysis data file generated by Elspec electrical metering hardware and read by PQSCADA Sapphire software. Alternatively, it can be a long-obsolete Palm Query Application used on old Palm OS devices to display web clippings. The Elspec .PQA format is highly proprietary and extremely dense, often containing millions of binary data points representing voltage, current, and harmonics. Because it requires a specialized application to interpret the structure, you cannot open it directly in standard spreadsheet tools. Users typically need to convert this data into CSV or XLSX formats to perform custom analysis or share reports with engineers who lack a PQSCADA license. The Palm OS version is similarly inaccessible today, essentially functioning as a compressed database of old HTML and images. Standard online converters fail to process .PQA files because the format is closed and undocumented. Often, only the original software can properly read or export the data. However, you can use convert.guru as a pragmatic workaround. Just drag and drop your file to identify the format, view its internal structure, and convert it when possible. If our analysis detects supported underlying text, HTML, or embedded tabular data, viewing or extracting the contents may still be possible.

Convert.Guru analyzes your PQA file, detects the exact format, and lets you read the text inside.

The PQA 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 PQA converter.
