JSON Lines Property Filter

Filter newline-delimited JSON object records by exact string representation of one selected property.

About this tool

Filter newline-delimited JSON object records by exact string representation of one selected property. Paste valid JSON, JSON Lines, CSV, or query data according to the labeled input. The example shows the expected transformation and any additional options. Processing happens locally in the browser, and malformed input or incompatible data structures produce a clear error. Inspect the result and validate it against the destination schema before using it in a production system. These tools do not send source data to a server.

How to use this tool

  1. Paste data into the labeled input.
  2. Provide a property name, range, or filter when requested.
  3. Run the tool, inspect its result, and copy or download it.
