How It Works

Every recording below is the real tool, running exactly as it does when you use it — nothing staged. Try the "network requests sent: 0" claim on the tool pages themselves, where it's actually being made.

JSON Formatter & Validator

Paste JSON and watch it format live, catch mistakes as you type, and copy the result — all without a round trip to a server.

1. Paste or type JSON into the input box — it formats live as you type.
2. Click "Show minified instead" to toggle between formatted and minified output.
3. Click "Copy" to copy whichever version is showing to your clipboard.

JWT Decoder

Paste a token to see its header and payload decoded instantly, plus an at-a-glance read on whether it's expired.

1. Paste a JWT into the token box.
2. Its header and payload appear decoded on the right, immediately.
3. If the token has an "exp" claim, an expiry line tells you whether it has already expired.

UUID & Hash Generator

Generate a fresh UUID v4 with one click, or hash any text with SHA-1/256/384/512 using your browser's own Web Crypto API.

1. Click "Generate new" for a fresh random UUID v4 — click again any time for another.
2. Type or paste text into the hash box to see SHA-1, SHA-256, SHA-384, and SHA-512 digests appear.
3. Click "Copy" next to the UUID to copy it to your clipboard.

JSON Formatter — Batch Mode (Pro)

Pro unlocks batch mode: format a whole stack of JSON documents at once, each one validated independently, still entirely in your browser.

1. Paste multiple JSON documents into the batch box, each separated by a line containing "---".
2. Click "Format all" — every item formats independently, with a ✓ or ✗ showing which ones parsed.
3. Click "Copy all formatted" to copy every successfully formatted item to your clipboard.

UUID & Hash Generator — Batch Mode (Pro)

Pro unlocks batch mode: generate dozens of UUIDs at once, or hash a whole list of values in one pass.

1. Set a count and click "Generate" to produce that many UUID v4 values at once.
2. Click "Copy all" to copy the whole batch to your clipboard.
3. Paste multiple lines into the batch hash box, pick an algorithm, and click "Hash all" to hash every line in one pass.

Regex Tester

Type a pattern and some text to test it against, and watch matches, capture groups, and a live replacement preview update as you type.

1. Type a pattern (and optional flags) into the pattern box.
2. Paste or type text into the test string box — matches and capture groups appear below it live.
3. Type a replacement to preview the result of replacing every match, then click "Copy" to copy it.

Timestamp Converter

Convert a Unix timestamp to a readable date, or a date to a Unix timestamp — both directions update live as you type.

1. Click "Now" to fill in the current Unix timestamp, or type/paste one of your own.
2. Its detected unit, ISO 8601, UTC, local time, and relative time appear immediately.
3. Type a date into the other box to convert it back to seconds and milliseconds.

CLI — Install & Explore

The same tools as a CLI for CI pipelines and scripts, where a browser tool can’t run headlessly. Install it globally and see the full command tree.

1. Install globally: `npm install -g vaultools` (or run it once with `npx vaultools`).
2. `vaultools --version` confirms it installed correctly.
3. `vaultools --help` lists every command — one per tool, plus the Pro batch variants.

CLI — A Real Session

A free command, a stdin pipe, and the real Pro batch gate — nothing staged, no license activated for this recording.

1. Pipe input directly, e.g. `echo '{...}' | vaultools json format` — every command accepts stdin or a file path.
2. Same for `vaultools jwt decode` — no browser required.
3. Batch/multi-value commands like `vaultools json batch` require a Pro license — this shows the real gate, not a staged success.
