Fixing JSON Fast
JSON breaks easily, and when it does, your workflow stops cold. The goal here is simple, find the exact issue, fix it fast, and return a clean, valid payload. No guessing and no rewriting everything, just quick diagnosis, precise corrections, and instant revalidation to keep the workflow moving.
Validator
Use an online JSON validator or formatter.
- Paste the JSON into a validator;
- Click Format/Validate;
- Read the first error, note the line and column, and what the parser expected.
- Fix that one issue only;
- Revalidate and repeat until it turns green.
LLM Assist
When you don't have time to hunt through lines of text.
- Paste the exact JSON payload and the error message into an AI assistant;
- Ask for a corrected JSON object or array only;
- If it still fails, paste the new validator error and iterate once or twice.
Validators show only the first error. Always fix from top to bottom, many problems chain from a single missing quote or bracket.
Common Mistakes Validators Catch
Most JSON errors disappear when you follow a few rules: use double quotes for all keys and strings, never leave trailing commas, keep booleans lowercase and unquoted, and treat numbers as real numbers, not strings. Use objects {} for a single item with fields and arrays [] for lists. If the format is invalid, n8n or any API will reject it immediately, exactly as JSON is meant to.
