HTML Formatter Guide
Reference for formatting HTML snippets before reviewing markup, CMS output, email templates, or copied page fragments.
Quick answer
Use the HTML Formatter to make pasted markup easier to read before reviewing, converting, or documenting it.
What this tool does
The formatter indents HTML so structure, nesting, attributes, and copied fragments are easier to inspect.
Step-by-step use
- Paste the HTML snippet.
- Format the markup.
- Review nesting, attributes, and text content.
- Copy the result if needed.
- Test the markup in the target environment.
Data handling and processing behavior
Processing is handled in the browser for this tool based on the current public implementation.
Examples
CMS output
Format copied HTML before checking whether headings and links are structured correctly.
Email template
Indent a small template fragment before editing table or link markup.
Review before publishing
For a CMS embed or email fragment, check links, image alt text, and tracking attributes after formatting. The same valid HTML can be rewritten by an email client or sanitized by a CMS, so treat the formatted output as a review aid and test it in the destination surface. For risky snippets, keep the original source beside the formatted copy.
Assumptions and limits
- Formatting does not validate accessibility or semantics.
- Broken markup may still need manual repair.
- Rendered behavior depends on CSS, JavaScript, and the target environment.
- Do not paste sensitive templates unless your data handling process allows it.
Common errors
Assuming formatted means valid
Readable HTML can still be invalid or inaccessible.
Ignoring rendering context
Email clients, CMS editors, and browsers can treat markup differently.
