What the HTML Formatter does
HTML Formatter: formats Status and Output from HTML Input. Example: the sample loaded on the page gives status Beautified.
Enter HTML Input and the HTML Formatter reports Status and Output. You can nudge a single number and watch the effect straight away.
Most people who open the HTML Formatter are developers debugging a payload. Spotting a malformed field is far quicker when the structure is laid out clearly.
This runs client-side, which means we never receive what you enter and could not retrieve it if asked.
The meaning of each field, the formula in use, and a worked example that starts from the default inputs are all further down.
What do the HTML Formatter fields mean?
The HTML Formatter uses 1 input. You do not have to fill everything in before seeing an answer; the starting values already produce one.
| Field | What to enter | Default |
|---|---|---|
| HTML Input | paste or type any amount of text | <div class="card"> <h1>Hello</h1> <p>World</p> </div> |
How does the HTML Formatter work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same formatted output.
The guard clauses run before the formula does, which is why mistakes surface next to the field.
Worked example
These are the values the HTML Formatter loads by default, and the result it produces from them. This is the worked example the page starts from, reproduced here so you can check the arithmetic.
| HTML Input | <div class="card"> <h1>Hello</h1> <p>World</p> </div> |
|---|
| Status | Beautified |
|---|---|
| Output | <div class="card"> <h1>Hello</h1> <p>World</p> </div> |
How to use it
- Paste your content into HTML Input.
- Because it recalculates as you type, you can dial a value in rather than guessing and re-running.
- You get Status and Output back.
- Copy Link puts the current inputs in the URL, so bookmarking it brings the same numbers back.
What this tool does not do
- Output follows the common convention for this format; a specific toolchain may have its own house style.
- Processing happens in your browser, so very large inputs are bounded by available memory.
- It does not account for anything you did not enter, by definition.
Frequently asked questions
HTML Input. That is the whole form. Every box already holds a working value, meaning you can explore the calculation before committing to real figures.
With the values loaded when the page opens, status comes out as Beautified. The figure is derived from the inputs above, so it updates whenever they do.
Nothing is logged. The tool is client-side code; your data stays where you entered it.
No. There is no account, no usage cap and no trial period. The site is funded by advertising rather than by charging for the tools.
Reliable for the case described. Where more than one convention exists, the method section says which one is used.
