Parse ISO 8601

How it works

Parsing and encoding run entirely in JavaScript here—no server sees your pasted content unless a tool explicitly says it fetches remote data.

Edge cases

  • Hidden whitespace or BOM characters can break otherwise valid input.
  • Line-ending differences (LF vs CRLF) may affect strict comparisons.
  • Large payloads are best tested in chunks to isolate the failing part.

Use this tool for

  • Formatting or minifying snippets before pasting into a repo or ticket.
  • Checking encodings (Base64, hex, URL) without third-party paste services.
  • One-off developer checks during debugging.
