Paste it. Read it. Move on.

8 tools for the response you cannot read, the token that expired, the two configs that should be identical. Every one of them runs in this tab — nothing you paste is uploaded.

Paste anything

Read here in your browser, never uploaded. JSON, a JWT, a timestamp, a URL, Base64 or a UUID are all recognised.

Read something

Make an opaque payload legible, and say plainly where it is malformed.

JSON FormatterJSON → JSONIndent, minify or sort a JSON document, and point at the line that broke it.JWT DecoderJWT → JSONRead a token's header and payload, with expiry shown as a real date.

Change the encoding

Move a value between the representations that carry it across the wire.

Base64text ⇄ base64Encode and decode Base64, including files to data URIs.URL Encodertext ⇄ %XXPercent-encode a value or a whole URL, and break a link into its parts.Timestamp Converterepoch ⇄ dateTurn a Unix timestamp into a date and back, in seconds or milliseconds.

Compare and match text

Find what changed between two versions, or what a pattern actually captures.

Regex Testerpattern × text → matchesHighlight what a pattern matches, and list what each group captured.Text Difftext × text → diffCompare two versions line by line and see what was added and removed.

Generate

Produce identifiers locally, so nothing that keys your data was ever seen elsewhere.

UUID Generator() → uuidMake random v4 or time-sortable v7 identifiers, one or a thousand.
