Color Palette JSON Exporter

The color palette JSON exporter turns an editable palette into a pretty-printed JSON array of uppercase hex values, ready to paste into code.

What is Color Palette JSON Exporter?

The color palette JSON exporter edits a palette and writes it out as JSON. You keep a list of colors and the panel beside it shows the result: a JSON array in which each entry is an uppercase six-digit hex string, indented two spaces and spread one value per line. A copy button lifts the whole thing onto the clipboard. It is the direct answer to a recurring chore, which is taking colours you chose visually and getting them into a place where code can read them without hand-typing hashes and commas.

The exact shape is worth stating because it decides where the output can be used:

• What comes out is a JSON array, not an object: it opens with a square bracket, holds a string per colour, and closes.
• The values are uppercased for consistency and indented two spaces, one per line, so the result reads cleanly in a diff.
• Because it is an array, order is preserved exactly as you arranged it, which is what a ramp, a chart series or anything positional depends on.

That array-versus-object distinction is the one real design choice in an exporter like this. An array keeps sequence, which is what you want for a ramp, a chart series or anything positional where the first colour means something different from the fourth. An object lets you reach a colour by name, which is what you want once values have roles attached. This tool produces the array form. If your target needs keys, the object and token generators cover that direction, and the CSS exporter produces declarations rather than data.

In practice the palette-to-json array route shows up wherever a list of values has to be consumed programmatically. Charting libraries take a series palette as an array. Test fixtures often snapshot a palette. Canvas and WebGL pipelines want plain values. Documentation sites generate colour tables from a JSON file. In all of those cases the array is exactly the right container, and generating it here removes the class of bug where a stray comma or a missing quote breaks a parse.

The workflow is deliberately short: edit the palette, watch the output update, copy it, paste it where it belongs. Because the editor is live there is no export step to remember, and the output can never disagree with what is on screen. Keeping the palette in one generated file rather than scattering literals through a codebase is the maintenance benefit, and starting from generated output rather than typing it by hand is what removes the typographic risk.

Two limits are worth knowing before you commit to this format:

• The output carries no names, so nothing in the file says which colour is a surface and which is an accent; that meaning lives only in the order and in your own documentation.
• It records hex only, with no rgb or hsl equivalents and no alpha channel, so a pipeline that needs those has to convert downstream.

For a clean palette to json array that code can read immediately, that narrowness is exactly what makes it paste-ready, so it remains the fastest way to export palette as json when the consumer expects a plain list of hex values, and where a target simply wants a hex array json file and nothing else, this produces it in one copy.

How to use Color Palette JSON Exporter

1. Edit the palette in the left-hand card, adding or removing rows as needed.
2. Read the JSON array in the panel beside it — it updates with every change.
3. Copy the array into a .json file, a module, a fixture or a build script.

When to use Color Palette JSON Exporter vs related tools

Use this exporter when a list of colour values needs to be machine-readable as an array. Use the object or token generators when keys and types are required, and the CSS exporter for stylesheet declarations. When keys and types are needed, the object generator and the token generator cover that direction, and the CSS exporter produces declarations rather than data.

Privacy & Security

This tool runs entirely in your browser — no data ever leaves your device. There is no server round-trip, no upload, no logging, and no account required. Your input is processed locally using client-side JavaScript and is never stored, transmitted, or accessible to anyone else. When you close the tab, everything disappears.
