Convert a file to HIS

To convert other file formats to the "History Log File" file type, you need software like Vaisala AviMet or a similar tool.

About HIS files

The .his file extension is a chameleon format used by dozens of unrelated software systems to store "history" data. It is most commonly associated with Vaisala AviMet weather logging systems, Her Interactive video games (as audio containers), and PerkinElmer digital X-ray imaging.

Because .his files are typically proprietary, they present significant access challenges. A .his file from a medical device is a high-bit-depth image, while one from a game is audio, and one from a server is a text log. Standard operating systems cannot distinguish between them, leading to errors when trying to open them with default applications like Windows Media Player or Microsoft Word. Users frequently encounter "file format not supported" errors or see garbled binary text when attempting to view them.

To use these files, you must convert them based on their origin:

For Data Logs (Vaisala, Trillian, Banking): Convert to CSV or XLSX to analyze trends in Microsoft Excel or PDF for secure archiving.
For Game Audio (Nancy Drew): Convert proprietary audio streams to WAV or MP3 for playback in standard players.
For Scientific Images (PerkinElmer, Hamamatsu): Convert raw sensor data to TIFF, PNG, or JPG for viewing in Adobe Photoshop without specialized hardware software.

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

Users also converted MOM, MLF and PTS files.
