No account, no network, no tracking. Paste, format, and go. Switch between a Text view for editing and a Tree view for exploring. Braceful validates while you type and tells you exactly where a document breaks, down to the line and the column. — WHAT MAKES BRACEFUL DIFFERENT — • Errors located, not just reported Invalid JSON gets the exact line and column of the problem, so you go straight to the character that broke it. • A tree you can actually navigate Objects and arrays collapse and expand, with keys, strings, numbers, booleans, and null each in their own color. • Big numbers survive Numbers are carried through as their original source text, so long integers and high-precision values are never silently rounded. • Your choice of indentation Pretty-print with two spaces, four spaces, or tabs — or minify the whole document to a single line. • Everything stays on the phone There is no account, no sign-in, no server round-trip, no ads, and no analytics. Your JSON never leaves the device. • Built to feel native A single screen with a floating action bar, quick Paste, Copy, Load Sample, and Clear actions, and a design that reads well in light and dark mode. — WHO IS BRACEFUL FOR? — • Developers checking an API response away from their desk • Anyone handed a wall of minified JSON who needs it readable right now • People working with data they would rather not paste into a website • Anyone who wants a JSON viewer that opens instantly and works on a plane — PRICING — Included: formatting with any indentation, minifying, live validation with line and column, the collapsible tree view, syntax colors, paste, copy, load sample, and clear — with no limits on document size or usage. Braceful Pro is a one-time in-app purchase — not a subscription — and adds importing JSON from Files, exporting the formatted result, search and filter across the tree by key, value, or path, sorting object keys A→Z for clean diffs, and escaping or unescaping JSON strings. — FEEDBACK — Made by a small indie team.
