Color CSV Exporter

The color CSV exporter writes a palette as a comma-separated table with one row per colour — index, hex, red, green, blue and HSL — ready to copy or download.

What is Color CSV Exporter?

The page is a palette editor on the left and a CSV card on the right. The editor holds five colours by default — a blue, a purple, a red, a green and an amber — and they can be changed, added or removed before exporting. The card prints the generated text in a scrollable block with two controls beneath it: a copy button and a Download .csv button that saves a file named palette.csv.

The format is fixed and worth knowing before the file is opened:

• The first line is a header row of six column names: index, hex, r, g, b and hsl.
• Each following line is one colour, numbered from one, with its hex value in upper case and its red, green and blue channels as whole numbers from zero to two hundred and fifty-five.
• HSL is written in the functional form a stylesheet would accept, and values are separated by commas with no quoting and no padding.

That shape is what makes the export useful rather than merely available. Spreadsheets open it with the header as column names, so a palette can be sorted, annotated with notes on where each colour is used, or handed to a reviewer who does not work in code. The same file drops into a design handoff without conversion, because the hex column and the HSL column hold values in the forms both sides already use.

A small detail matters for anyone round-tripping the palette: the HSL figure is a formatted string, not three separate numeric columns, so sorting by hue in a spreadsheet means splitting that column first. The red, green and blue channels are separate, which makes them the practical columns for arithmetic or charting.

What the page does not offer is a choice of format. The editor exports CSV only — no JSON, no SVG, no PNG card and no token file — and there is no column selection, no delimiter setting and no way to paste a palette in for re-export. The colours come from the editor or they do not come at all.

The practical case for a table rather than an image is that a table can be edited. A palette exported as CSV can be annotated with where each colour is used, sorted by hue after the HSL column is split, merged with a second palette to check for near-duplicates, or handed to a reviewer who works in a spreadsheet. That is a different job from exporting a swatch image for a document, and it is what a color csv exporter is for: the same colours in rows, with the numbers separated so they can be used rather than only looked at.

Limits are worth knowing before the file leaves the page:

• One palette and one format: this page exports CSV only — no JSON, no SVG, no PNG card and no token file.
• Six fixed columns, with no column selection, no delimiter setting and no way to paste a palette in for re-export.
• The HSL figure is a formatted string rather than three separate numeric columns, so sorting by hue in a spreadsheet means splitting that column first, where the red, green and blue channels are the practical columns for arithmetic or charting.

Read plainly, as a hex rgb csv export with the palette spreadsheet use in mind, the file it writes is exactly the table described: an export colors to csv at one row per colour, and the simplest palette csv export on the site.

How to use Color CSV Exporter

1. Edit the palette in the left-hand card — the default five can be changed, added to or removed.
2. Read the CSV text in the right-hand card, which updates as the palette changes.
3. Copy the text or press Download .csv to save the file as palette.csv.

When to use Color CSV Exporter vs related tools

Use this when a palette has to leave the browser as a table — a spreadsheet for review, a handoff to a designer or a check of the channel values. Use the SVG or PNG palette exporters when the output should be an image, or the palette importer when a list is coming back the other way. When the output should be an image instead, the SVG palette exporter produces vector markup and the PNG palette generator draws a strip; when a list comes back the other way, the palette importer is the way in.
