Cell Style Example

// STEP 1: Create a new workbook
const wb = XLSX.utils.book_new();

// STEP 2: Create data rows and styles
let row = [
	{ v: "Courier: 24", t: "s", s: { font: { name: "Courier", sz: 24 } } },
	{ v: "bold & color", t: "s", s: { font: { bold: true, color: { rgb: "FF0000" } } } },
	{ v: "fill: color", t: "s", s: { fill: { fgColor: { rgb: "E9E9E9" } } } },
	{ v: "line\nbreak", t: "s", s: { alignment: { wrapText: true } } },
];

// STEP 3: Create worksheet with rows; Add worksheet to workbook
const ws = XLSX.utils.aoa_to_sheet([row]);
XLSX.utils.book_append_sheet(wb, ws, "readme demo");

// STEP 4: Write Excel file to browser
XLSX.writeFile(wb, "xlsx-js-style-demo.xlsx");

border	top		{ style: BORDER_STYLE, color: COLOR_STYLE }
	bottom		{ style: BORDER_STYLE, color: COLOR_STYLE }
	left		{ style: BORDER_STYLE, color: COLOR_STYLE }

COLOR_STYLE {object} Properties

Colors for border, fill, font are specified as an name/value object - use one of the following:

Color Prop	Description	Example
rgb	hex RGB value	{rgb: "FFCC00"}
theme	theme color index	{theme: 4} // (0-n) // Theme color index 4 ("Blue, Accent 1")
tint	tint by percent	{theme: 1, tint: 0.4} // ("Blue, Accent 1, Lighter 40%")

BORDER_STYLE {string} Properties

Border style property is one of the following values:

• dashDotDot
• dashDot
• dashed
• dotted
• hair
• mediumDashDotDot
• mediumDashDot
• mediumDashed
• medium
• slantDashDot
• thick
• thin

Border Notes

Borders for merged areas are specified for each cell within the merged area. For example, to apply a box border to a merged area of 3x3 cells, border styles would need to be specified for eight different cells:

• left borders (for the three cells on the left)
• right borders (for the cells on the right)
• top borders (for the cells on the top)
• bottom borders (for the cells on the left)
