Why JSON Validation Matters for DevOps Configuration

We often think of YAML as the “DevOps language,” but JSON underpins the most critical parts of the cloud.

• AWS IAM Policies (Allow vs Deny).
• Terraform State files (tfstate).
• CloudWatch Log filters.

A syntax error in a JSON policy can lock you out of your account.

The Problem with “Generic” Validators

Most “JSON Checker” websites send your data to a backend server. Do not paste your IAM keys or Terraform state into a random website.

The Solution: Client-Side Verification

You need a tool that runs strictly in Javascript, in your browser, without network requests.

• Syntax Check: Finds missing commas or unclosed braces.
• Formatting (Prettify): Turns minified log lines into readable structures.
• Minify: Compresses large policies to fit into AWS 4KB limits.
