About HTML Entity Encoder/Decoder
The HTML Entity Encoder/Decoder from ToolsOfIndia gives developers, bloggers and email template builders a quick, dependable way to get answers without wrestling with formulas. Encode and decode the full set of HTML entities, including the named, decimal and hex forms, so any character - including currency, maths and arrows - can be shown literally on a page. The tool handles the less-than, greater-than, ampersand and quote characters that break markup, and the special symbols that need an entity to render. Developers use it to embed code, bloggers to show symbols, and because everything runs locally, nothing is uploaded. The tool also decodes an entity string back to the character for inspection. It is the entity tool that pasting a special symbol always needs. Everything is processed locally in your browser, so pasted code, tokens or client data never leaves your device - no uploads, no logs, no tracking. Real-world uses include encoding a currency symbol for a page, showing a code block with angle brackets, and decoding an entity string. Results update as you type, so you can play what-if games instead of redoing the whole calculation.
