IAM Policy Beautifier

A minified IAM policy pulled from a CLI response, a CloudTrail event, or a squashed Terraform state file is technically readable but painful to review — one long line (or a handful of them) with no indentation to show which brace belongs to which statement. IAM Policy Beautifier takes that JSON, parses it, and re-prints it with consistent, readable indentation so nested statements, conditions, and principal blocks are visually structured the way you would hand-format them yourself.

Formatting only requires the pasted text to be valid JSON — it does not require the document to already be a well-formed IAM policy. That distinction matters because you often want to beautify a document specifically to review whether it is well-formed. So if the JSON parses but the shape looks off (no Statement array, a statement with no Effect, and similar), the tool still formats the JSON as-is and shows a separate structural warning alongside it, rather than refusing to format until the policy is perfect.

If the pasted text is not valid JSON in the first place — a trailing comma, a missing brace, an unescaped quote inside a string — beautifying stops there and you get a specific line and column pointing at the syntax problem, the same detection technique used by the IAM Policy JSON Syntax Validator in this category.

Choose 2-space or 4-space indentation; either is purely cosmetic and has no effect on how the policy evaluates once attached to a role, user, or resource.

• Pretty-prints minified or inconsistently indented policy JSON.
• 2 or 4-space indent, selectable.
• Formats any valid JSON, not just structurally valid IAM policies — with a separate warning when the structure looks off.
• Line/column JSON syntax errors when the text does not parse at all.
• One-click copy of the formatted output.
• Sample minified policy to try instantly.
• 100% client-side — nothing is uploaded.

1. Paste minified or messy policy JSON, or click the sample.
2. Pick 2-space or 4-space indent.
3. Click Beautify.
4. Copy the formatted result with the copy button.

Example 1 — one-line policy. {"Version":"2012-10-17","Statement":[{"Effect":"Allow","Action":"s3:GetObject","Resource":"*"}]} becomes a fully indented, multi-line document.

Example 2 — valid JSON, incomplete policy. {"Statement":[]} formats fine but shows a structural warning: missing Version and an empty Statement array.

Example 3 — broken JSON. A copy-paste that dropped a closing brace reports a specific line/column syntax error instead of formatting.

• Turns unreadable minified policies into reviewable documents instantly.
• Formats first, validates structure second — you are never blocked from seeing the JSON just because the policy shape is imperfect.
• Pinpoints JSON syntax errors by line and column instead of a generic failure.
• Private — formatting runs entirely in your browser.
