Visual Studio Code (VSCode) is a popular code editor used by many developers. One of its many features is the ability to format and beautify JSON files. By default, JSON files are displayed in a multi-line format that can make it difficult to read and understand. However, it is possible to convert the JSON file to a single line format using a few simple steps.
In this article, we will take a look at how to convert a JSON file to a single line format using Visual Studio Code.
Step 1: Open the JSON file in Visual Studio Code
The first step is to open the JSON file you want to convert in Visual Studio Code. If you already have a JSON file open in the editor, you can skip this step. If not, you can open a new file by clicking on File > Open File and selecting the JSON file you want to convert.
Step 2: Install the "EditorConfig" extension
In order to convert the JSON file to a single line format, we will be using the "EditorConfig" extension. This extension allows you to configure the formatting options for different file types, including JSON.
To install the "EditorConfig" extension, click on the Extensions icon on the left-side panel in Visual Studio Code and search for "EditorConfig". Select the extension from the list of results and click on the Install button.
Step 3: Create an .editorconfig file
The next step is to create an .editorconfig file in the same directory as the JSON file you want to convert. This file will contain the formatting options for the JSON file.
To create the .editorconfig file, right-click on the JSON file in the Visual Studio Code file explorer and select "New File". Name the file ".editorconfig" and press Enter.
Step 4: Add the following code to the .editorconfig file
Now that the .editorconfig file has been created, we can add the formatting options for the JSON file.
Add the following code to the .editorconfig file:
root = true
[*.json]
indent_style = space
indent_size = 1
end_of_line = lf
charset = utf-8
insert_final_newline = false
trim_trailing_whitespace = false
This code sets the indent style to spaces, the indent size to 1, the end of line character to line feed (lf), the character set to UTF-8, and disables the insertion of a final newline and the trimming of trailing whitespaces.
Step 5: Format the JSON file
The final step is to format the JSON file to a single line format. To do this, right-click on the JSON file in the Visual Studio Code file explorer and select "Format Document".
The JSON file should now be converted to a single line format, making it easier to read and understand.
Conclusion
Converting a JSON file to a single line format in Visual Studio Code is a simple process that can be done in a few steps. By using the "EditorConfig" extension and creating an .editorconfig file, you can easily configure the formatting options for JSON files and make them easier to read and understand.
Example:
Before:
{
"name": "John Doe",
"age": 32,
"address": {
"street": "123 Main St",
"city": "New York",
"state": "NY",
"zip": "10001"
},
# Alternative methods for formatting JSON in Visual Studio Code
