-### Use convenience conversion and parsing functions
-
-Wrap all extracted numeric data into safe functions from [`youtube_dl/utils.py`](https://github.com/ytdl-org/youtube-dl/blob/master/youtube_dl/utils.py): `int_or_none`, `float_or_none`. Use them for string to number conversions as well.
-
-Use `url_or_none` for safe URL processing.
-
-Use `try_get` for safe metadata extraction from parsed JSON.
-
-Use `unified_strdate` for uniform `upload_date` or any `YYYYMMDD` meta field extraction, `unified_timestamp` for uniform `timestamp` extraction, `parse_filesize` for `filesize` extraction, `parse_count` for count meta fields extraction, `parse_resolution`, `parse_duration` for `duration` extraction, `parse_age_limit` for `age_limit` extraction.
-
-Explore [`youtube_dl/utils.py`](https://github.com/ytdl-org/youtube-dl/blob/master/youtube_dl/utils.py) for more useful convenience functions.

-#### More examples
-
-##### Safely extract optional description from parsed JSON
-```python
-description = try_get(response, lambda x: x['result']['video'][0]['summary'], compat_str)
-```
-
-##### Safely extract more optional metadata
-```python
-video = try_get(response, lambda x: x['result']['video'][0], dict) or {}
-description = video.get('summary')
-duration = float_or_none(video.get('durationMs'), scale=1000)
-view_count = int_or_none(video.get('views'))
-```
