# Sitemap validator
With the "Sitemap validator" tool, you can check your site's Sitemap file contents. The validation is based on the [file requirements](https://yandex.com/support/webmaster/en/controlling-robot/sitemap.md).
{% note info %}
Make sure that `Sitemap` is available and returns the HTTP status with the 200 OK code. To do this, use the [Server response check](https://webmaster.yandex.com/tools/server-response/) tool. If the server response takes more than 10 seconds, the file isn't downloaded by the tool and isn't taken into account by the robot when crawling. In this case, you should reduce the server response time.
{% endnote %}
To check the file contents, go to the [Sitemap validator](https://webmaster.yandex.com/tools/sitemap/) page and follow these steps:
1. Add a file using one of these methods:
- The file contents (the **text** option). Copy the file contents to the field. If there are validation errors, you can edit the file and recheck it.
- The file itself (the **file** radio button). Upload the file from the site directory or drag it to the field.
- The file link (the **URL** radio button). Enter the file link in the field, for example `https://example.com/sitemap.xml`.
1. Click the **Check** button.
If any validation errors are found, see the [Sitemap errors reference](https://yandex.com/support/webmaster/en/error-dictionary/sitemap.md) section.
## What to do next
Upload your `Sitemap` file in Yandex Webmaster (**Indexing** → **Sitemap files**) so that the indexing bot can regularly process it and detect changes on your site. In Yandex Webmaster, you can see when the indexing bot crawls the file and let it know that the file has been updated. Learn more in the [Sitemap files](https://yandex.com/support/webmaster/en/indexing-options/sitemap.md) section.
