Docify

Developer tools that run in your browser

Sixteen named, client-side utilities for JSON, encodings, IDs, time, and strings. This page is an index — open a tool to run it. Nothing is uploaded.

Docify’s developer tools run in the browser with the API named on each page: JSON.parse / JSON.stringify, Papa Parse, js-yaml CORE_SCHEMA, btoa/atob, encodeURI / encodeURIComponent, crypto.randomUUID, crypto.subtle.digest, ECMAScript RegExp, and Horner on BigInt. JWT signatures are never verified. MD5 is a checksum only. Cron is Vixie crontab(5) five-field syntax, not Quartz.

What this hub is

An internal-linking map of the developer-classified tools already on the homepage. Each card names the algorithm and a hard limit so you can pick the right page. It is not a search box, an API, or a server-side sandbox.

Data formats

JSON Formatter

JSON.parse then JSON.stringify. Prettify is 2-space indent; minify is one compact line. Standard JSON only (ECMA-404 / RFC 8259).

Open

CSV to JSON

Papa Parse with header, skipEmptyLines, and dynamicTyping, then 2-space JSON.stringify. Not Excel and not JSON-to-CSV.

Open

YAML to JSON

js-yaml 5 load with CORE_SCHEMA (YAML 1.2 Core). yes/NO stay strings. Comments drop. Not YAML 1.1 and not !!merge.

Open

Encode and decode

Base64

UTF-8 text via btoa/atob (RFC 4648). Files encode through a FileReader data-URL payload. Download is text/plain, not a binary restore.

Open

URL Encoder

encodeURI for a full URL; encodeURIComponent for a query value (RFC 3986). Spaces become %20, not +.

Open

HTML Encoder

Escapes & < > " ' as &amp; &lt; &gt; &quot; &#39; (ampersand first). Decode is those five names plus numeric character references, not the full HTML5 table.

Open

Identifiers and checksums

UUID Generator

RFC 4122 version 4 via crypto.randomUUID() (36-character hyphenated hex). Count 1–100. Not v1/v3/v5/v7 or ULID.

Open

Hash Generator

SHA-256 and SHA-1 via crypto.subtle.digest (FIPS 180-4). MD5 is RFC 1321 in JavaScript — checksum only, not a password hash, not HMAC.

Open

JWT Decoder

Compact JWS only (three base64url segments). Header and payload are pretty-printed JSON. The signature is shown, never verified. Not JWE or JWKS.

Open

Time and schedules

Unix Timestamp

POSIX seconds since 1970-01-01T00:00:00Z via JavaScript Date. Seconds use new Date(n * 1000); milliseconds use new Date(n). toISOString is UTC. No unit auto-detect.

Open

Cron Explainer

Vixie crontab(5) five-field syntax only. DOM/DOW OR when both are restricted. Not Quartz (no seconds field, ?, L, W, or #) and not a next-run calculator.

Open

Strings and values

Regex Tester

ECMAScript new RegExp(pattern, flags) then exec. Flags gimsuy only. Without g, first match only. Not PCRE, Python, or POSIX.

Open

Line Sorter

Split on LF after CRLF/CR normalize. Sort is Array.prototype.sort (UTF-16, not localeCompare). Unique keeps the first Set key.

Open

Number Base Converter

Integers between bases 2–36. Horner parse on BigInt; output is BigInt.prototype.toString(radix). Not Number.parseInt and not two’s complement.

Open

Color Converter

Opaque sRGB hex (#RGB / #RRGGBB), rgb(r, g, b) integers 0–255, and hsl(h, s%, l%) via CSS Color Module Level 4. Not named colors or Display P3.

Open

Lorem Ipsum

Fixed three-paragraph corpus: mid-1960s Letraset dummy plus Cicero De finibus 1.10.32–33. Not a random-word dictionary.

Open

Short comparisons that point back to the live tools. They are not thin clones of the pages above.

FAQ

Do these developer tools upload my data?
No. Each page runs in your browser (JSON.parse, crypto.subtle.digest, Papa Parse, js-yaml, and the other named APIs on that page). Files, tokens, and hashes stay on the device.
Which tools belong on this hub?
The 16 encoding, data, ID, time, and string utilities listed below — the same set marked DeveloperApplication on the homepage. Word counting, case conversion, Markdown, and text diff are indexed on /text-tools/. Images-to-PDF and the PDF stamp are indexed on /pdf-tools/.
Does the JWT decoder prove a token is valid?
No. /jwt-decoder/ only splits a compact JWS into three base64url segments and pretty-prints the header and payload as JSON. The signature bytes are shown. There is no HMAC, RSA, or JWKS check, and JWE (five segments) is rejected.
Is the hash tool a password hasher?
No. SHA-256 and SHA-1 are unkeyed hex digests from crypto.subtle.digest. MD5 is an RFC 1321 checksum in JavaScript, not SubtleCrypto. None of them are HMAC, bcrypt, Argon2, or a KDF.
