Tree Query Language file

File type category:
Source code and script file

Date updated: September 28, 2026

Tree Query Language is a query language for navigating and retrieving information from tree-structured, semistructured data. A TQL file stores the text of a query rather than the XML data being queried.

TQL files are used with software that supports Tree Query Language to query XML files and other compatible data. The file is a source-code or script file, and its results depend on the data and the TQL implementation used to process it.

How to open tql file?

A TQL file can be opened as plain text in a text editor to view or edit its query. To run the query, open it with software that supports Tree Query Language; a general-purpose editor will not execute it.

How to convert tql file?

There is no general-purpose conversion for a TQL file. Its query can be rewritten manually in another query language when an equivalent language and compatible data source are available, but this may require changes to the query syntax and structure.
