# Modifying item language
When indexing content, Coveo can detect [several languages](https://docs.coveo.com/en/1956/) on readable pages and leverage them to fill the `language` [metadata](https://docs.coveo.com/en/218/).
However, you may encounter situations where Coveo has detected no or too many languages.

You may want to address this problem by using an [indexing pipeline extension (IPE)](https://docs.coveo.com/en/206/) script to manipulate the `language` metadata.
This post-conversion extension script sample sets the `language` metadata to `English` if many or no languages have been detected.

**Post-conversion extension script sample**:

```python
# force English when many or no languages have been detected
language = document.get_meta_data_value('language')
if (not language) or (language and ';' in language[0]):
  document.add_meta_data({'language': 'English'})
```
