When should I start with this collection?
Start here when your work begins with pasted data, config files, tokens, or headers and you want to inspect or convert them in sequence.
Collection
Developer Data Workflows
Format, inspect, convert, and validate payloads in the browser when you need a fast dev workflow without opening heavier tooling.

← HomeWhy this collection exists
This collection groups the TeaFun tools that are most useful when a workflow starts with raw data. It helps you move from pasted payloads to a verified result quickly without juggling several different apps.
Common use cases
- Validate JSON, reshape config files, and move between formats without leaving the browser.
- Inspect tokens, headers, and logs when debugging an API response or support issue.
- Chain related data tools together when one answer turns into a broader troubleshooting path.

FAQ
How is this different from the broader developer category?
The developer category shows every dev tool. This collection narrows the path to the tools that usually belong in the same payload-debugging or data-conversion workflow.
