What This Tool Does
Encode or decode HTML entities when moving text between raw content, templates, and rendered markup.
Use it to inspect or transform input quickly, then carry validated output into code, tests, or API requests.
Common Use Cases
- Escape user-provided text before embedding in HTML snippets.
- Decode stored entity-heavy content for editing.
- Inspect escaped payloads copied from logs or APIs.
Common Pitfalls
- Entity decoding can unexpectedly turn safe text into active markup if rendered unsafely.
- Different systems may use named and numeric entities inconsistently.
