Extract text from TurboTax or Trimble files (TDX)
To convert TDX data files to another format, you need Intuit TurboTax or other Data software.
To convert other file formats to the "Tax & Database Files" file type, you need software like Intuit TurboTax or a similar tool.
The .TDX file extension is a heavily fragmented format utilized by several entirely unrelated industries. Its most recognized use is as a Tax Data Exchange file generated by Intuit TurboTax, which stores user financial and tax return metadata. In the engineering and surveying world, it is actively used by Trimble RealWorks as a 3D laser scan project database. Under the hood, the Trimble variant is built entirely on SQLite. Other legacy uses include the TYDEX (Tire Data Exchange) standard, Chinese stock data platforms (TongDaXin), Trainz Simulator indexes, and texture dictionaries for vintage Tony Hawk's Pro Skater video games.
Because .TDX has no universal standard, it creates severe compatibility roadblocks. TurboTax .TDX files are proprietary and encrypted, locking your financial data securely inside Intuit's ecosystem - you cannot read them without the exact software year that generated them. Meanwhile, Trimble RealWorks databases are massive, often exceeding hundreds of gigabytes, making them extremely difficult to share, archive, or process on low-end hardware. Legacy game and stock data formats are completely unreadable by modern operating systems without custom, community-built parsers.
If you need to access the data trapped inside a .TDX file, format conversion is critical. For Trimble SQLite-based databases, convert to SQL or CSV to run custom queries or migrate spatial data to other GIS platforms. For TurboTax data, exporting or printing to PDF or .PDF/A is the only reliable way to archive your financial records long-term. For game textures, target PNG or DDS. Drag and drop your file here to analyze and convert it - free, online, and without installing software.

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 TDX converter.
