About this free flatten nested json arrays tool
Flatten nested array levels while keeping object values intact. Developer utilities inspect or transform data locally rather than contacting the address or service shown in your input. Use fictional samples while checking a format, keep credentials out of shared screenshots and validate the result against the receiving system. Successful parsing does not establish trust, security or schema correctness.
A practical example
A concrete example uses json input: [1,[2,[3]]]. The result is [ 1, 2, 3 ].
Before you rely on the result
Processes pasted input on your device, not a live website. Keep the original and review the output. Up to 200,000 characters. JSON syntax must be valid; deep inputs over 60 levels are rejected. Numeric conversions can lose precision; inspect identifiers before converting.
