HTML entity converter
HTML entity converter encodes or decodes entity notation in text. Check the worked example and encoding layers when comparing reserved characters with markup.
HTML entity converter helps you encode or decode HTML entity notation when checking how reserved characters are represented inside text and markup contexts. Start with a representative sample of your actual task. Read the form labels and the returned value before replacing text, a link, or a code fragment that is already in use.
How to use HTML entity converter
- Paste a short text sample.
- Choose Encode or Decode.
- Select Submit and inspect ampersands and angle brackets carefully.
Worked example
In this implementation the Encode branch calls entity encoding twice: a plain ampersand can become &. One decoding pass does not necessarily reverse that double encoding.
Limits and checks
Do not treat the result as universal sanitization for HTML, JavaScript, CSS, or URLs. Those contexts need different handling. Compare a representative sample before inserting the output into an existing document or template.
Frequently asked questions
Does the appearance prove the result is correct?
No. Compact or readable output does not check every rule of its destination. Compare syntax, values, and behavior in an appropriate environment before using the result in production.
Why can a plain ampersand become &?
The Encode branch applies entity encoding twice in this implementation. Check the number of encoding layers before using the output; one decoding pass may leave an encoded ampersand behind.
