JSON, CSV, and AMF tools
Choose by the change your data needs: JSON checks, table conversion, or AMF decoding.
Choose by task
Check and arrange JSON
Use JSON Validator to check syntax before you investigate a failed import. It does not check your application's schema. Choose JSON Formatter when you only need indentation. It preserves number tokens and duplicate members, so readable output does not resolve duplicate names.
JSON Comparator compares two inputs. JSON Sorter orders object keys or object rows by a selected value. The sorter rejects duplicate members and numbers that cannot survive its numeric conversion. Quote precise identifiers before sorting them. Read the JSON numbers and duplicate keys guide before trusting large integers or repeated names.
- JSON ValidatorCheck whether text is strict JSON or JSON Lines in your browser. Errors name the exact line, column, and cause, such as a trailing comma.
- JSON FormatterFormat and inspect JSON in your browser while preserving numeric text, key order, and string escapes. Your data stays on your device.
- JSON ComparatorCompare two JSON documents in your browser. Lists changed, added, and removed keys by path, and ignores key order and whitespace.
- JSON SorterSort JSON object keys, or order an array of objects by one property, in your browser. Rejects duplicate keys and numbers that would lose precision.
Move table data between formats
Use CSV and JSON Converter when the receiving system needs another format. Its CSV to JSON mode uses Cell delimiters, Row delimiters, and Format. Choose Array of dictionaries for named columns or Array of arrays for positional rows. Read the CSV and JSON workflow guide before changing types or flattening nested values.
Choose CSV Separator Changer when the table stays CSV. Set Input separator and Output separator explicitly. The changer removes CSV quotes and does not restore them by default. Turn on Quote every output field when a cell contains the new separator. That option does not double inner quotes.
- CSV and JSON ConverterTurn CSV rows into JSON objects, or JSON back into CSV, in your browser. Handles quoted commas and line breaks, keeps leading zeros, and flattens nested JSON.
- CSV Separator ChangerChange a CSV delimiter, such as semicolon to comma, in your browser. Parses quoted cells line by line and can quote every output field.
Decode an AMF payload
AMF Decoder reads serialized AMF bytes; it does not format pasted JSON. Select the byte representation that matches your payload. Inspect decoded values before moving them into another data format.
