To convert other file formats to the "Scientific & Testing Data File" file type, you need software like Molecular Devices ImageXpress or a similar tool.
About HTD files
The .HTD file extension is primarily used as a High-throughput screening metadata file generated by specialized laboratory equipment, such as the Molecular Devices ImageXpress system or PerkinElmer Opera Phenix. In this context, it stores critical metadata about automated cellular imaging. Another frequent use case is as a recorded HTTP traffic data file, often generated by application security testing software like HCL AppScan or performance testing tools like OpenText LoadRunner. In niche industrial sectors, it acts as a Geotechnical materials test data file for Humboldt HMTS or a Heat Transfer Data file.
The main disadvantage of .HTD files is extreme fragmentation and proprietary lock-in. A biological .HTD file cannot be opened by an HTTP network testing tool, and neither can be read natively by a standard operating system. Viewing or extracting this data typically requires the original, highly expensive enterprise software, creating severe bottlenecks for cross-team collaboration. Furthermore, the HTTP traffic variant is often just a ZIP-compressed archive containing raw network logs, which remains unreadable until extracted or parsed.
To make this data accessible for downstream analysis or auditing, converting to open data formats is essential. Convert .HTD to CSV or JSON for seamless database imports, Python analysis, and data visualization. For reading network logs, convert to TXT or XML.
Convert.Guru analyzes your HTD file, detects the exact format, and lets you read the text inside.

The HTD 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 HTD converter.
