Validation & Error Navigation

JSON Toolkit validates your input continuously with jsonc-parser as you type.

What to expect

• The status bar updates in real time with valid or error state.
• Parse errors include a human-readable message plus line/column details.
• Use Jump to error to move the editor caret directly to the failing token.
• The tree view only renders once your input parses successfully.

Notes

• JSONC is supported, so comments and trailing commas are accepted.
• Even after actions like Escape/Unescape or Diff workflows, validation is re-run so status stays trustworthy.
