Convert JSON to YAML with Python
Python Convert JSON to YAML
In Python, there are several ways to convert JSON data into YAML format. This tutorial will walk you through the step-by-step process of converting JSON to YAML using different methods.
Method 1: Using the pyyaml
Library
The pyyaml
library provides a simple and straightforward way to convert JSON to YAML. You can install it using pip
by running the following command:
Once installed, you can use the following code to convert JSON data to YAML:
The above code reads the JSON data from a file called data.json
, converts it to YAML format using the dump()
function from the yaml
module, and then saves the converted data to a file called data.yaml
.
Method 2: Using the ruamel.yaml
Library
Another popular library for converting JSON to YAML is ruamel.yaml
. Unlike pyyaml
, ruamel.yaml
preserves the order of keys in dictionaries. You can install it using pip
by running the following command:
Here’s an example of how to use ruamel.yaml
to convert JSON to YAML:
In this code, the JSON data is loaded from the data.json
file, converted to YAML format using the round_trip_dump()
function from ruamel.yaml
, and then saved to a file called data.yaml
.
Method 3: Using the json2yaml
Command-Line Tool
If you prefer a command-line tool for converting JSON to YAML, you can use the json2yaml
package. It allows you to convert JSON files directly from the command line without writing any code.
First, install json2yaml
using pip
:
Once installed, you can use the following command to convert a JSON file to YAML:
Replace input.json
with the path to your JSON file and output.yaml
with the desired path for the YAML file.
Conclusion
In this tutorial, we explored three different methods for converting JSON to YAML in Python. You can choose the method that best suits your needs, whether it’s using the pyyaml
or ruamel.yaml
libraries, or utilizing the json2yaml
command-line tool. Whichever method you choose, you now have the tools to effortlessly convert JSON data into YAML format. Happy coding!
