About this tool

What Pipeline does

Small developer tasks often require several conversions in sequence. Pipeline keeps those steps together, passes each result to the next operation, and stores reusable pipeline definitions in this browser without uploading the data.

Common uses

  • Decode Base64 and immediately format the JSON
  • Extract a JSONPath value from a decoded API payload
  • Save repeatable local conversion recipes

Privacy and limitations

Pipeline definitions and optional history are stored only in this browser. Input and output never leave the current tab.

Validate important output in the actual language, database, or target platform.

Frequently asked questions

Which steps are available?

The first release supports Base64 decode and encode, JSON format and minify, and JSONPath extraction.

Can I save a pipeline?

Yes. Named pipeline definitions are stored in localStorage and can be removed at any time.

Is processing sent to a server?

No. Every pipeline step runs in this browser.
