excel4node

An OOXML (xlsx) generator that supports formatting options

Installation:

npm install excel4node

Usage:

Instantiate a new workook

var xl = require('excel4node');
var wb = new xl.WorkBook();

Add a new WorkSheet to the workbook

var ws = wb.WorkSheet('New Worksheet');

Add a cell to a WorkSheet with some data.
Cell can take 3 data types: String, Number, Formula
Cell takes two arguments: row, col

ws.Cell(1,1).String('My String');
ws.Cell(2,1).Number(5);
ws.Cell(2,2).Number(10);
ws.Cell(2,3).Formula("A2+B2");
ws.Cell(2,4).Formula("A2/C2");

Set Dimensions of Rows or Columns

ws.Row(1).Height(30);
ws.Column(1).Width(100);

Create a Style and apply it to a cell

  { top:{ style:'thin', color:'CCCCCC' }, right:{ style:'thin', color:'CCCCCC' }, bottom:{ style:'thin', color:'CCCCCC' }, left:{ style:'thin', color:'CCCCCC' }, diagonal:{ style:'thin', color:'CCCCCC' } }

var myStyle = wb.Style();
myStyle.Font.Bold();
myStyle.Font.Italics();
myStyle.Font.Underline();
myStyle.Font.Family('Times New Roman');
myStyle.Font.Color('FF0000');
myStyle.Font.Size(16);
myStyle.Font.Alignment.Vertical('top');
myStyle.Font.Alignment.Horizontal('left');
myStyle.Font.WrapText(true);

var myStyle2 = wb.Style();
myStyle2.Font.Size(14);
myStyle2.Number.Format("$#,##0.00;($#,##0.00);-");

var myStyle3 = wb.Style();
myStyle3.Font.Size(14);
myStyle3.Number.Format("##%");
myStyle3.Fill.Pattern('solid');
mystyle3.Fill.Color('CCCCCC');
myStyle3.Border({
	top:{
		style:'thin',
		color:'CCCCCC'
	},
	bottom:{
		style:'thick'
	},
	left:{
		style:'thin'
	},
	right:{
		style:'thin'
	}
});

ws.Cell(1,1).Style(myStyle);
ws.Cell(1,2).String('My 2nd String').Style(myStyle);
ws.Cell(2,1).Style(myStyle2);
ws.Cell(2,2).Style(myStyle2);
ws.Cell(2,3).Style(myStyle2);
ws.Cell(2,4).Style(myStyle3);

Freeze Columns to prevent moving when scrolling horizontally
First example will freeze the first two columns (everything prior to the specified column);
Second example will freeze the first two columns and scroll to the 8th column.

ws.Column(3).Freeze();
ws.Column(3).Freeze(8);

Insert an image into a WorkSheet
Image takes one argument which is relative path to image from node script
Image can be passed optional Position which takes 4 arguments
img.Position(row, col, [rowOffset], [colOffset])
row = top left corner of image will be anchored to top of this row
col = top left corner of image will be anchored to left of this column
rowOffset = offset from top of row in EMUs
colOfset = offset from left of col in EMUs

Currently images should be saved at a resolution of 96dpi.

var img1 = ws.Image(imgPath);
img1.Position(1,1);

var img2 = ws.Image(imgPath2).Position(3,3,1000000,2000000);

Write the Workbook to file or node response

wb.write("My Excel File.xlsx");
wb.write("My Excel File.xlsx",res);

ToDo

• Add Date functions
• Add ability to apply styles to cell range
• Add ability to merge cells
• Add Text formatting options (cell with more than one font size/color/decoration)
