The same tools, in your terminal.

Format JSON, hash strings, encode Base64, decode JWTs, convert YAML — all from a single pipe-friendly CLI. No signup, no telemetry, just stdout.

$npx consolelog-tools json-format file.json

Zero-install via npxFull stdin/stdoutSingle bundled binary

Install

Run once with npx

$npx consolelog-tools <command>

Or install globally for a shorter consolelog binary

$npm i -g consolelog-tools

$pnpm add -g consolelog-tools

$bun add -g consolelog-tools

Requires Node.js ≥ 18. The package bundles every dependency, so installs are fast and the dependency tree stays out of your node_modules.

Pipelines

Every command reads from a file, an inline string, or stdin — and writes to stdout. So they all compose with each other and with anything else in your shell.

Hash a generated UUID

$consolelog uuid | consolelog hash --algo sha256

Generate a UUID, then SHA-256 hash it in one shell pipeline.

Pretty-print a curl response

$curl -s https://api.example.com/users | consolelog json-format

No more grepping minified JSON — pipe straight from curl.

YAML → minified JSON

$consolelog yaml-to-json config.yaml | consolelog json-minify > config.min.json

Convert + minify in a single line, write to disk.

I/O contract

Every command resolves its input in this order, then writes the result to stdout:

1A file path, if the first positional arg points at an existing file.
2An inline string, if the first arg isn't a file.
3Whatever's on stdin, if data was piped in.

Errors go to stderr with a non-zero exit code, so shell pipelines surface failures correctly.
