Debugging API responses
Copy a minified response body from your backend logs or DevTools, paste it here, and instantly see the structure. No need to install a CLI tool or set up jq aliases.
Format, mampat, sahkan dan visualkan JSON dalam beberapa saat. Semua berjalan dalam pelayar anda — data tidak pernah meninggalkan peranti.
Tidak. Semua penghuraian dan pemformatan berlaku dalam pelayar anda. Data tidak pernah meninggalkan peranti.
Pelayar moden boleh mengendalikan 1-10 MB dengan lancar. Fail sangat besar (>20 MB) mungkin perlahan; gunakan alat CLI untuknya.
Pantas, peribadi, tiada pemasangan — hurai JSON terus dalam pelayar anda.
Satu klik untuk mengembangkan JSON padat kepada bentuk mudah dibaca dengan indentasi dan penonjolan sintaks automatik.
Buang semua ruang dan baris baru untuk menghasilkan JSON paling ringkas bagi pemindahan API.
Apabila penghuraian gagal, kami menunjukkan baris dan lajur tepat serta konteks sekeliling untuk penyahpepijatan pantas.
Paparan berstruktur yang boleh dikembangkan/dilipat. Panjang tatasusunan dan bilangan kunci dipaparkan dalam baris.
Semua pengiraan dibuat dalam pelayar anda. Data tidak pernah dimuat naik ke mana-mana pelayan.
Seret fail.json untuk memuat, dan eksport hasil kembali sebagai.json dengan satu klik.
Pure browser-side JSON parsing — no upload, no log line, no third-party API call.
Paste a JSON string into the editor or drop a .json file from disk. The browser reads it via FileReader directly into JavaScript memory — no XHR, no fetch, no upload. Even multi-megabyte payloads are fine; the parser streams them in chunks if needed.
We hand the string to JSON.parse — the same V8 / SpiderMonkey / JavaScriptCore parser your browser uses for every fetch response. If parsing fails, the position of the bad character is reported with line and column so you can fix it instantly. No regex hacks, no ambiguous error messages.
Once parsed, the result is rendered as a collapsible tree using virtualised DOM nodes — so a 100,000-key object stays smooth at 60 fps. You can collapse arrays, copy paths, and navigate by keyboard.
Pretty-print with 2 / 4 / tab indent, minify to a single line, copy to clipboard, or download the cleaned file. The transformation runs in your browser — the resulting bytes never leave the page.
Real situations where browser-only JSON parsing wins.
Copy a minified response body from your backend logs or DevTools, paste it here, and instantly see the structure. No need to install a CLI tool or set up jq aliases.
After Base64-decoding the middle segment of a JWT, paste the resulting JSON to see the claims, expiry, and any custom fields. The token never touches a server other than the one issued it.
Re-format a malformed .json config (Tailwind, ESLint, package.json, tsconfig) so it stops failing in CI. Catches trailing commas and duplicate keys that hand-written configs accumulate.
Open two browser tabs side by side, paste the old and new schema. Use the tree view to spot added or removed fields without diffing escaped strings.
Your JSON often contains real customer records, API keys, JWT secrets, internal IDs, and PII. Most online JSON formatters POST your payload to their server — meaning a third party logs every field you paste. iKit's JSON Decoder runs as JavaScript in your browser tab, so the parser sees your data, but no server ever does.

Pretty-print, validate, and structurally diff messy JSON with three methods that work in any browser.
When a JSON document needs to embed binary data inline, Base64 is the encoding that makes it possible.

Biasanya kerana petikan hilang, tanda koma berlebihan, atau penggunaan petikan tunggal. Buka tab "Ralat" untuk melihat lokasi tepat.
Pada masa ini hanya JSON ketat mengikut RFC 8259 disokong. Beritahu kami jika anda memerlukan sokongan JSON5 / JSONC.
Selepas muatan pertama, sebahagian besar sumber dicache oleh pelayar, jadi ia berfungsi dengan atau tanpa sambungan rangkaian.
