How to Format YAML Files - Step by Step Guide

Step 1

Input Unformatted YAML

Got messy YAML files? Just paste your poorly formatted YAML content. The formatter handles files with inconsistent indentation, missing spaces, and irregular structure.

Example: Messy YAML Input

Here's what unformatted YAML looks like: 😅

# Messy YAML file
app:name:"My App"
version:1.0.0
config:{debug:true,port:3000}
database:{host:"localhost",port:5432,ssl:false}
features:["auth","logging","monitoring"]
Step 2

See Automatic Formatting

Here's where the magic happens! 🎉 The formatter automatically applies proper YAML syntax, consistent indentation, and clean spacing. Choose between 2-space or 4-space indentation.

Beautifully Formatted Output

Your messy YAML becomes clean and readable:

# Messy YAML file
app:
  name: "My App"
  version: 1.0.0

config:
  debug: true
  port: 3000

database:
  host: "localhost"
  port: 5432
  ssl: false
Step 3

Choose Formatting Options

Customize the output with different indentation levels, line spacing, and formatting styles. Options include minified or beautified output.

•
Indentation: 2 spaces, 4 spaces, or tabs
•
Line Width: Control maximum line length
•
Array Format: Flow style or block style
•
Comments: Preserve or remove comments
Step 4

Copy or Download Clean YAML

Perfect! Copy the formatted YAML to your clipboard or download it as a .yml file. The clean format improves readability and reduces errors.

•
Improved readability and maintainability
•
Consistent team coding standards
•
Reduced syntax errors and debugging time
•
Better version control diffs
