Check

When is the result reliable?

How does JSON error explainer calculate?

JSON error explainer uses this visible logic: JSON.parse prüft den Payload; bei SyntaxError werden Message, Position, Zeile/Spalte, Kontext und der wahrscheinlich nächste Fix ausgegeben. Example values and common mistakes are shown next to the tool.

Do inputs stay local?

Yes. The calculation runs in the browser. Toolwise does not send inputs to a server or load external calculation modules.

What should I do next?

Copy the result or pass it locally to File transfer time if you want to continue the workflow.
