Keep a chart you can return to

Use the right file for viewing, reporting or editing.

The browser tab is a workspace, not permanent storage. There is no account, automatic saving or cloud sync. Download a JSON project before closing the tab if you want to continue later.

JSON is the editable project

It stores the title, grid dimensions, RGB palette, cells and fabric settings. It does not include the original image. Importing it restores the chart, but rebuilding from the picture requires choosing that source image again. Import replaces the current chart and can be undone during the session.

SVG is the viewing chart

The vector export contains the grid, letter symbols, ten-cell guides and an RGB legend. It can be enlarged in a compatible viewer without turning into a blurry screenshot. It is not a PDF or a promise of a particular physical print scale. Use your viewer's own print settings if you choose to print it.

CSV is the symbol matrix

Each row records chart symbols by column, with empty cells left blank. It does not contain image pixels or a brand thread catalogue. Keep the SVG or JSON palette alongside the matrix to understand what each letter means.

Respect the source

Use pictures you are entitled to transform and share. A local conversion does not grant permission to redistribute somebody else's artwork. Review the project title and file contents before sharing them publicly.
