title: Ignoring Code
---
Prettier offers an escape hatch to ignore a block of code or prevent entire files from being formatted.
## Ignoring Files
To exclude files from formatting, add entries to a `.prettierignore` file in the project root or set the [`--ignore-path` CLI option](cli.md#ignore-path).
## JavaScript
A JavaScript comment of `// prettier-ignore` will exclude the next node in the abstract syntax tree from formatting.
For example:
```js
matrix(
1, 0, 0,
0, 1, 0,
0, 0, 1
)
// prettier-ignore
matrix(
1, 0, 0,
0, 1, 0,
0, 0, 1
)
```
will be transformed to:
```js
matrix(1, 0, 0, 0, 1, 0, 0, 0, 1);
// prettier-ignore
matrix(
1, 0, 0,
0, 1, 0,
0, 0, 1
)
```
## JSX
```jsx
{/* prettier-ignore */}
```
## HTML
```html
hello world
```
## CSS
```css
/* prettier-ignore */
.my ugly rule
{
}
```
## Markdown
```markdown
Do not format this
```
### Range Ignore
_available in v1.12.0+_
This type of ignore is only allowed to be used in top-level and aimed to disable formatting for auto-generated content, e.g. [`all-contributors`](https://github.com/kentcdodds/all-contributors), [`markdown-toc`](https://github.com/jonschlinkert/markdown-toc), etc.
```markdown
| MY | AWESOME | AUTO-GENERATED | TABLE |
|-|-|-|-|
| a | b | c | d |
```
## GraphQL
```graphql
{
# prettier-ignore
addReaction(input:{superLongInputFieldName:"MDU6SXNzdWUyMzEzOTE1NTE=",content:HOORAY}) {
reaction {content}
}
}
```
