Query Converter

The Query Converter assists users transitioning from Legacy Search syntax (Censys Search Language) to Platform syntax (Censys Query Language, or CenQL). Enter a Legacy Search query into the Query Converter to identify syntax differences and view recommended changes to correct your query.

This page explains how to use the Query Converter in the Platform web UI. You can also convert queries via API.

Query Converter in the search bar

You can input Legacy Search queries in the search bar. The built-in query converter will automatically turn them into valid Platform queries.

Query Converter tab

Follow the steps below to use the Query Converter:

Go to the Censys Platform Homepage and click the Query Converter tab.
Enter a Legacy Search query into the Original Query field and click Convert.
