DevUnescape FAQ
What kinds of text can Smart Decode handle automatically?
It can auto-detect escaped strings, JSON, URL encoding, HTML entities, Base64 text, and JWT payloads in a single input panel.
When should I use Raw text mode or Expand stringified JSON values?
Use Raw text mode when you only want escape cleanup without URL, HTML, Base64, or JWT detection. Enable Expand stringified JSON values when JSON fields contain nested JSON strings you want converted into objects or arrays.
What happens if the input is invalid or cannot be decoded cleanly?
DevUnescape keeps the original text, avoids destructive changes, and shows a notice so you can adjust the input or switch modes.
