Tool workspace

Use this workspace like a mini app: enter input, review output, run examples, and copy or download results.

Tip: start with an example to confirm input/output structure, then replace values with your own data.
Tool workspace will load when it enters the viewport to reduce initial load cost.

Practical Notes

Base64 Encode/Decode is designed for quick, repeatable workflows. Start with an example, verify output, then adapt for your own data.
