React-Data-Export

⚠️ A complete re-write is coming soon (we won't need xlsx package anymore (It will be backward compatible)⚠️

🆕 I am re-writing complete excel api in JavaScript, please consider contributing or putting your ideas here https://github.com/securedeveloper/javascript-excel (After finishing will update this library)

(:exclamation::exclamation::exclamation:The purpose of having a new library is that open source libraries either does not support styling and rest functionality in excel or they are too heavy to consider)

A data export library built with and for React.

npm install react-data-export --save

Cell Style

Cell styles are specified by a style object that roughly parallels the OpenXML structure. The style object has five top-level attributes: fill, font, numFmt, alignment, and border.

Style Attribute	Sub Attributes	Values
fill	patternType	"solid" or "none"
	fgColor	COLOR_SPEC
	bgColor	COLOR_SPEC
font	name	"Calibri" // default
	sz	"11" // font size in points
	color	COLOR_SPEC
	bold	true or false
	underline	true or false
	italic	true or false
	strike	true or false
	outline	true or false
	shadow	true or false
	vertAlign	true or false
numFmt		"0" // integer index to built in formats, see StyleBuilder.SSF property
		"0.00%" // string matching a built-in format, see StyleBuilder.SSF
		"0.0%" // string specifying a custom format
		"0.00%;\\(0.00%\\);\\-;@" // string specifying a custom format, escaping special characters
		"m/dd/yy" // string a date format using Excel's format notation
alignment	vertical	"bottom" or "center" or "top"
	horizontal	"bottom" or "center" or "top"
	wrapText	true or false
	readingOrder	2 // for right-to-left
	textRotation	Number from 0 to 180 or 255 (default is 0)
		90 is rotated up 90 degrees
		45 is rotated up 45 degrees
		135 is rotated down 45 degrees
		180 is rotated down 180 degrees
		255 is special, aligned vertically
border	top	{ style: BORDER_STYLE, color: COLOR_SPEC }
	bottom	{ style: BORDER_STYLE, color: COLOR_SPEC }
	left	{ style: BORDER_STYLE, color: COLOR_SPEC }
	right	{ style: BORDER_STYLE, color: COLOR_SPEC }
	diagonal	{ style: BORDER_STYLE, color: COLOR_SPEC }
	diagonalUp	true or false
	diagonalDown	true or false

COLOR_SPEC: Colors for fill, font, and border are specified as objects, either:

• { auto: 1} specifying automatic values
• { rgb: "FFFFAA00" } specifying a hex ARGB value
• { theme: "1", tint: "-0.25"} specifying an integer index to a theme color and a tint value (default 0)
• { indexed: 64} default value for fill.bgColor

BORDER_STYLE: Border style is a string value which may take on one of the following values:

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

Borders for merged areas are specified for each cell within the merged area. So 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

Dependencies

This library uses file-saver and xlsx and using json-loader will do the magic for you.
