Support — RLSAND JSON Editor

Everything you need to keep editing.

Getting started, formats and file handling, iCloud sync, API Projects — and a form to reach us when you're still stuck. Most questions have quick answers below.

Getting started

RLSAND JSON Editor works the moment you open it — no account, no sign-in. It's a document-based app: your files stay your files, in the Files app on iPhone and iPad or the Finder on Mac.

1

Open, paste, or fetch a document

Open a file from Files or the Finder, paste JSON straight from the clipboard as a new document, or fetch one from a URL. The app reads JSON, JSONC, JSON5, and JSON Lines / NDJSON, and can import and export CSV.

2

Pick the view that fits

Tree for structure, Table when the document is really a spreadsheet, Raw for hand editing, Split to see both at once. All views stay synchronized over the same document, and undo/redo works everywhere.

3

Fix and format

Validation runs as you type, with errors located by line and column. A broken document stays visible — Repair explains what's wrong in plain language and previews a safe fix before applying it. Prettify, minify, and sort keys are one tap away.

4

Turn on iCloud sync (optional)

iCloud sync is off by default — separate toggles in Settings cover API Projects, saved credentials, and recents/snippets, all stored in your own iCloud account.

FAQ

The questions we get most often. If yours isn't here, drop us a note below.

Where are my documents stored? Do they touch your servers?

Your documents live in your files, on your device — the app is document-based and local-first. We have no account system and no server that ever sees your data. Apart from optional iCloud sync, the app only makes a network request when you ask it to: fetching a URL you enter, sending an API Project request to an endpoint you configured, importing or refreshing an API Project from an address, or sending an AI request you start to Apple's Private Cloud Compute or to your own AI provider. See the Privacy Policy.

Do you collect analytics or usage data?

No. RLSAND JSON Editor contains no analytics, no telemetry, no crash-reporting service, and no third-party analytics, advertising or tracking SDKs. There is nothing to opt out of.

Which formats does it support?

Strict RFC 8259 JSON, JSONC (JSON with comments), the common JSON5 config subset, and JSON Lines / NDJSON. CSV can be imported into Table view and exported back out. YAML is not supported — if you have an OpenAPI spec in YAML, convert it to JSON first.

Does one purchase cover iPhone, iPad, and Mac?

Yes. It's a single universal app — buy it once and it unlocks on iPhone, iPad, and Mac under the same Apple ID. The Mac version is a real native Mac app, not a port or a web wrapper.

Does it use AI?

Yes, optionally, from version 1.1: Ask Your JSON, AI Assist edits, Explain with AI, and generators. AI help runs only when you invoke it, and you can turn it off in Settings. With Apple Intelligence it runs on your device (iOS, iPadOS or macOS 26 or later on eligible devices), or on Apple's Private Cloud Compute for larger requests on 27 or later (by default the app asks first). Every AI screen shows where a request will go before anything leaves your device. If you add your own Anthropic, OpenAI, Gemini or Grok key, requests go to that provider instead. Documents you mark Private stay on your device either way, and nothing changes in your document until you choose to apply it. The rest of the app works without AI. Details are in the Privacy Policy.

How does iCloud sync work?

It's opt-in and off by default, with three independent toggles: API Project structure syncs through your private CloudKit database, saved credentials go through iCloud Keychain, and recent files / snippets sync through iCloud key-value storage. Secrets never ride along in sync records — they live only in the Keychain.

Can I import from Postman, cURL, or OpenAPI?

Yes. Paste a cURL command and it becomes a request; import Postman collections and OpenAPI/Swagger definitions (JSON format). A few cURL options aren't supported yet: -F multipart uploads, -b cookies, and -k insecure mode.

What authentication do API Projects support?

The common schemes — API keys, bearer tokens, and basic auth — with credentials stored in the Keychain and redacted everywhere they're displayed. OAuth 2.0 flows and cookie-based sessions aren't supported yet; sessions are ephemeral by design.

How large a file can it handle?

Large ones. The app is performance-tested to open a 5 MB document in under half a second and keep the tree scrolling at 60fps. Bigger files work too — they just take proportionally longer to open.

Is there an Android or Windows version?

RLSAND JSON Editor is built natively for Apple platforms — iPhone, iPad, and Mac. If that changes we'll announce it here.

How do refunds work?

App Store purchases are refunded by Apple, not by us. reportaproblem.apple.com is the path. If you're stuck, contact us and we'll help you frame the request.

Troubleshooting

The most common issues and their fixes. Try the matching one before sending us a note.

iCloud sync isn't syncing

Check that both devices are signed in to the same Apple ID with iCloud Drive enabled, and that the matching sync toggle (API Projects, credentials, or recents/snippets) is on in Settings on both devices. First sync after enabling can take a minute.

A file won't open or shows as broken

A malformed document is kept visible on purpose — Repair explains the problem and points at the likely spot. If nothing renders at all, check the format: YAML isn't supported, and binary formats need converting to JSON first.

Fetch from URL won't load

Check that the URL returns raw JSON rather than an HTML page, and that it's served over HTTPS — plain HTTP is allowed only for localhost and .local addresses on your own network.
