How this CSS formatter helps
Before and after formatting
Paste compact, copied, or hard-to-read CSS into the input pane. FormatPaste cleans common paste artifacts first, then formats the code into readable output that is easier to scan, debug, share, or copy into your editor.
Common CSS formatting use cases
Use it for quick snippets from documentation, AI chat output, Stack Overflow answers, config examples, API responses, old files, minified blocks, and code that picked up line numbers or markdown fences while being copied.
Safe paste reminder
FormatPaste is built for speed, but you should avoid pasting passwords, API keys, tokens, private keys, recovery codes, customer data, or other secrets into any online formatter. Use local tools for sensitive code.
