About DTI files
The .DTI extension is shared by two distinct file types, creating a frequent point of confusion for users. Most commonly, it represents Spectrophotometer Kinetics Data generated by scientific instruments like the Thermo Scientific Helios or sensors from Data Translation Inc. (now part of Measurement Computing). These files contain time-series data or absorbance values critical for laboratory analysis. The major issue here is proprietary lock-in; opening these files often requires specific legacy software like Logger Pro or custom LabVIEW drivers. If you don't have access to the original instrument's computer, the data is essentially trapped. Converting these technical files to CSV or XLSX is the standard workflow, allowing you to analyze the raw numbers in Microsoft Excel or import them into Python for plotting.
Alternatively, in South Korea, a .DTI file may be a Korean Electronic Tax Invoice. These are structured XML files adhering to the national e-Tax Invoice Standard, often associated with software like SmartBill. While XML is technically human-readable text, the raw code is cluttered with tags and difficult to interpret visually. For accounting and auditing purposes, users almost always need to convert these invoices to PDF for easy reading, printing, and archiving, or to HTML to view them in a standard web browser without specialized financial software.
Convert.Guru analyzes your DTI file, detects the exact format, and lets you read the text inside.
If you want to convert DTI file to SEC, CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT or DB, you can use Logger Pro or similar software from the "Scientific Data Storage" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to DTI, try Logger Pro or another comparable tool in the "Scientific Data Storage" category.
The DTI 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 DTI converter.
