Example Usage & Test Cases

Encode a heading
Input Scenario:
<h1>Tom & Jerry</h1>
Generated Result:
&lt;h1&gt;Tom &amp; Jerry&lt;/h1&gt;

How It Works

1

Scans the input text and replaces reserved characters (&, <, >, ", ') with their named HTML entity equivalents.

2

For decoding, safely parses entities back into their literal text characters using the browser's own HTML parser.

3

Runs in your browser, so your text is not sent to an Alona Tool server.
