What is Conditional Formatting?

Conditional Formatting Formatter is a free, browser-based tool that helps you make messy data readable. Generate conditional-formatting rules. It's built for speed and privacy: Everything runs locally in your browser — your data is never uploaded to a server. No sign-up, no installs, and no daily limits.

How to use Conditional Formatting

1Paste your data into the input panel or drop a file.
2Choose how it should look — indentation, pretty-print vs. minify, and structure options.
3Copy the formatted output or download it for use in your project.

Features

Toggle between pretty-print and minify
Consistent, configurable indentation
100% client-side — no upload, fully private
Free with no account, no watermark, and no daily limit
Works on large inputs, limited only by your device's memory
Load a sample, then copy, download, or share your result

Common errors

Formatting is used before validating, so syntax errors remain hidden.
Minified output is pasted where humans still need to review it.
Tabs and spaces are mixed in a way that makes diffs noisy.
A formatter is expected to fix semantic data problems that require cleaning instead.

How it works

1Parses or tokenizes the data input.
2Applies consistent spacing, indentation, or compacting rules.
3Returns output without changing the meaning of the data.

Frequently asked questions

How do I use Conditional Formatting?: Paste or drop your data into the workspace, adjust the options to fit your data, then copy or download the result. Generate conditional-formatting rules.
Is my data uploaded or stored anywhere?: No. Everything runs locally in your browser — your data is never uploaded to a server. Nothing is sent to a server, so it's safe to use with private or sensitive data.
Is Conditional Formatting Formatter free?: Yes — it's completely free with no account, no sign-up, no watermark, and no daily usage limits.
What's the maximum file size?: There's no hard limit imposed by the tool. Because processing happens in your browser, the practical ceiling is your device's available memory — most everyday files work instantly.
