# Convert Postman Collection to OpenAPI Yaml

Download this tool:

```
npm i postman-to-openapi -g
```

On Postman Click on Export and export the collections as JSON.

Then on CLI run:

```
p2o ./path/to/PostmantoCollection.json -f ./out_openapi_.yml
```

This will create the OpenAPI Schema at `out_openapi_.yml.`

Open this file in a text editor of your choice and update the basePathUrl and any other variables.
