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");

			Ex: `"m/dd/yy"` // string a date format using Excel's format notation

`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

mediumDashed

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)
