Why Your JSON Keeps Breaking (and How to Fix It in Seconds)
Trailing commas. Single quotes instead of double. An unquoted key that looked fine in your editor's syntax highlighting but isn't actually valid JSON. If you write JSON by hand or copy it out of a log line, you've hit at least one of these -- usually at the worst possible moment, mid-deploy, with a parser throwing a cryptic "Unexpected token" error and no indication of where.
The fix isn't to memorize the JSON grammar. It's to get a validator that tells you the exact line and column, in plain English, and -- for the common cases -- just fixes it for you. That's the whole reason our JSON tool shows a caret under the failing character and offers a one-click repair for trailing commas, quote style and unescaped comments, instead of leaving you to guess.
