Decode named, decimal, and hexadecimal HTML entities into readable text while detecting unknown or malformed entity sequences.
HTML Entity Decoder transforms text for safer use in web, API, configuration, spreadsheet, or serialized-data workflows. It reports conversion counts, output size, syntax issues, and a data integrity score.
Escaping improves format safety, but it does not replace input validation, authentication, authorization, or contextual security review.
Example input: <div>Tom & Jerry</div>. The result area shows the converted value plus integrity, size, and validation metrics.
Processing happens locally in the browser. The tool calculates character analysis, syntax validation, output byte size, expansion, and format-specific warning signals.
Escaping improves format safety, but it does not replace input validation, authentication, authorization, or contextual security review.
Paste encoded text such as < or < and decode it back into readable characters.
The content may have been escaped for safe display. Decoding restores the intended symbols.
Yes. Decimal entities like < and hexadecimal entities like < can be decoded.
Preserve them if you need the original source, or inspect them as possible malformed entities.
Paste the copied entity text into the decoder and use mixed mode for named and numeric entities.
| Module | Purpose |
|---|---|
| Conversion Engine | Applies the selected escape, unescape, encoding, or parsing rules. |
| Syntax Validation | Detects malformed entities, invalid escapes, quote errors, or parser failures. |
| Data Integrity Score | Scores whether the output is safe and complete for the selected context. |
| Security Notes | Highlights XSS, injection, parser, and spreadsheet import risks. |
| Export Tools | Copies or downloads TXT, CSV, and JSON reports. |
