Output is generated with JSON.stringify, so it is always valid JSON. Empty fields are omitted automatically.

About this tool

IconVault's package.json Generator builds a valid package.json visually, no memorized field names required. Pick a project type (app, library or CLI) for sensible presets, then fill in name, version, description, author and license, add or remove scripts, dependencies and devDependencies with versions, set engines, and watch the live JSON preview update as you type. Copy it or download the finished file when you are done.

It is free, needs no signup, and runs 100% client-side. The honest note: the tool produces clean, valid JSON with correct structure, but it cannot know your exact dependency versions, so double check version ranges against the registry before you publish or commit.
