Apa yang dilakukan JSON Diff?
JSON Diff membantu membandingkan masukan langsung di browser serta menjelaskan hasil dan batasannya dengan jelas. Kemampuan yang telah diverifikasi: Structural JSON comparison, JSON path output, Array index comparison, Local parsing.
Choose structural JSON diff or text diff?
Use JSON Diff when value types, keys, and array positions matter but formatting does not. Use Text Diff when whitespace, comments in a non-JSON format, or exact source lines are part of the change.
Bagaimana cara menggunakannya?
- Paste valid JSON into Original JSON and Changed JSON, or load the sample pair.
- Choose Compare values and select Convert. Whitespace and property order do not create changes because both inputs are parsed first.
- Review each +, −, or ~ path, then copy or download the comparison.
Contoh masukan dan keluaran nyata
A changed scalar and an appended array item
Masukan
Original: {"version":1,"tags":["local"]}
Changed: {"version":2,"tags":["local","fast"]}Keluaran
~ $.version: 1 → 2
+ $.tags[1] = "fast"The comparison follows parsed object keys and array indexes, so indentation changes alone produce no result.
Kesalahan umum dan perbaikannya
| Gejala | Kemungkinan penyebab | Perbaikan |
|---|---|---|
| The output is empty and the page reports a JSON parse error. | One input contains invalid JSON such as a trailing comma or an unquoted key. | Validate both documents first and correct the reported syntax before comparing them. |
| A reordered array produces several changes. | Array positions are significant; the tool does not match moved objects by an ID field. | Sort arrays by a stable key before comparing when order should not matter. |
Important behavior of JSON Diff
Batas khusus alat ini: Array order remains significant, so moved items appear as changes.
Standar dan referensi implementasi
- RFC 8259 — The JavaScript Object Notation (JSON) Data Interchange Format (opens in a new tab)Defines the JSON grammar accepted before values are compared.
JSON Diff — FAQ
Does the JSON Diff upload my input?
No. Processing runs in the current browser tab, and the page does not send tool input to a KitLumi processing endpoint.
What input does the JSON Diff accept?
It accepts two valid JSON documents. The workspace checks the input and reports malformed or unsupported values before it produces a result.
What does the JSON Diff produce?
It produces path-based additions, removals, and changed values. Copy and download controls appear when the output format supports them.
What limitation should I know?
Array order remains significant, so moved items appear as changes.
Apa yang berubah?
Pembaruan substantif: JSON Diff: Added Structural JSON comparison, JSON path output, Array index comparison, Local parsing, responsive controls, explicit runtime disclosure, and task-specific examples and limitations.
