Common questions
Do you upload my JSON anywhere?

Your input is not sent to a server.
What does the filter do?
You can match fields by JSON path and values (regex), and
apply simple numeric conditions for numbers.
When does Table or CSV work best?
Table and CSV work best for arrays of objects (or an object
that contains such an array).
