Extract text from Drake tax data files (D10)
To convert D10 tax files to another format, you need Drake Tax or other Database software.
To convert other file formats to the "Tax Preparation File" file type, you need software like Drake Tax or a similar tool.
A .D10 file is a proprietary data file created by Drake Software, a widely used professional tax preparation suite. These files store highly sensitive client tax return information, financial data, and form preparation states for specific tax years. Typically, this format is managed exclusively using Drake Tax, though older legacy software like H&R Block Deduction Pro also generated files with this extension.
Because it is a closed, proprietary format, you cannot natively open a .D10 file in standard applications like Microsoft Word or Microsoft Excel. This creates a major vendor lock-in disadvantage for accountants. If a firm switches to different tax software, or if a client requests a digital copy of their return, the raw .D10 file is practically useless. Retaining these files often requires maintaining an expensive, active software subscription just to access historical client data.
To overcome these limits, it is strongly recommended to convert the data. The best target formats are PDF for immutable document retention and client sharing, or CSV for migrating basic financial data and demographic tables to a new system. Note that proprietary tax form logic and complex formatting will be lost during any data export.
Converting .D10 files directly without the original software is notoriously difficult because the internal database structure is heavily obfuscated.
Convert.Guru analyzes your D10 file, detects the exact format, and lets you read the text inside.

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 D10 converter.
