# Working with Properties
## Yaml to Properties
To convert to property file format, use `--outputformat=props` or `-o=p`. Porting the comments from the `yaml` file to the property file is still in progress, currently line comments on the node values will be copied across. 
Given a sample file of:
```yaml
# block comments don't come through
person: # neither do comments on maps
name: Mike # comments on values appear
pets:
- cat # comments on array values appear
food: [pizza] # comments on arrays do not
```
then
```bash
yq -o=p sample.yaml
```
will output:
```
# comments on values appear
person.name = Mike
# comments on array values appear
person.pets.0 = cat
person.food.0 = pizza
```
