Data file
What is a .xfdf file?
A .xfdf file is a XML Forms Data Format. This is a data file — structured information used by a program rather than read directly.
How to open a .xfdf file
- Start with the program that produced it; that's almost always the right tool.
- Open it in a text editor to see whether it's readable text or binary.
- For database formats, DB Browser for SQLite or LibreOffice Base can often import it.
The registry records this extension against XML Forms Data Format, so software from that family is the most likely match.
How to convert a .xfdf file
- If you can view the data, exporting to .csv is usually the most portable option.
