How to convert JSON to YAML

JSON and YAML are both used for storing data. JSON typically for serializing data and YAML typically for configuration files. You can easily convert JSON files to YAML with Easy Data Transform:

• Install Easy Data Transform on your PC or Mac, if you haven’t done so already. It will only take a minute. There is a fully functional free trial and you don’t have to give us your email or sign up to anything.
• Start Easy Data Transform. Make sure the Auto Run button is pressed in.

• Drag the JSON file you wish to convert onto Easy Data Transform. The file name should end in .json. A pink input item will be added.
• Notice in the Right pane that the JSON data has has been automatically ‘flattened’ into a table. You can set the Format drop-down in the Right pane to Long or Wide, depending on whether you want the tables to have more rows or more columns.
• Ensuring the pink input item is selected, click the To File button in the Left pane (scroll to the bottom of the Left pane).

• A window will appear. Set the new file name and location. Select YAML file as the file type.

• A green output item is added and selected.

• The YAML file is created immediately, no need to ‘run’ anything.
• You can change the YAML file Encoding in the Right pane.

Example JSON input:

[
  {
    "CustomerID": "ALFKI",
    "CompanyName": "Alfreds Futterkiste",
    "ContactName": "Maria Anders"
  },
  {
    "CustomerID": "ANATR",
    "CompanyName": "Ana Trujillo Emparedados y helados",
    "ContactName": "Ana Trujillo"
  },
  {
    "CustomerID": "ANTON",
    "CompanyName": "Antonio Moreno Taquería",
    "ContactName": "Antonio Moreno"
  }
]

Example YAML output:

--
-
  CustomerID: ALFKI
  CompanyName: Alfreds Futterkiste
  ContactName: Maria Anders
-
  CustomerID: ANATR
  CompanyName: Ana Trujillo Emparedados y helados
  ContactName: Ana Trujillo
-
  CustomerID: ANTON
  CompanyName: Antonio Moreno Taquería
  ContactName: Antonio Moreno

If you have many files to convert you can do it using the batch processing feature.

As well as changing file format, Easy Data Transform also allows you to combine 66 transforms (such as join, filter and dedupe) to quickly and easily create a wide range data transformations.
