html-to-xlsx

node.js html to xlsx transformation

Transformation only supports html table and several basic style properties. No images or charts are currently supported.

var conversion = require("html-to-xlsx")();
conversion("<table><tr><td>cell value</td></tr></table>" }, function(err, stream){
  //readable stream to xlsx file
  stream.pipe(res);
});

Supported properties

• background-color - cell background color
• color - cell foreground color
• border-left-style - as well as positions will be transformed into excel cells borders
• text-align - text horizontal align in the excel cell
• vertical-align - vertical align in the excel cell
• width - the excel column will get the highest width, it can be little bit inaccurate because of pixel to excel points conversion
• height - the excel row will get the highest height
• font-size - font size
• colspan - numeric value that merges current column with columns to the right
• rowspan - numeric value that merges current row with rows below.
• overflow - the excel cell will have text wrap enabled if this is set to scoll.

Options

var conversion = require("html-to-xlsx")({
  /* use rather dedicated process for every phantom printing,
	  "dedicated-process" strategy is quite slower but can solve some bugs
	  with corporate proxy, default is "phantom-server" */
  strategy: 'phantom-server', // 'dedicated-process' or 'phantom-server'
  /* number of allocated phantomjs processes */
	numberOfWorkers: 2,
	/* timeout in ms for html conversion, when the timeout is reached, the phantom process is recycled */
	timeout: 5000,
	/* directory where are stored temporary html and pdf files, use something like npm package reaper to clean this up */
	tmpDir: "os/tmpdir",
	/* optional port range where to start phantomjs server */
  portLeftBoundary: 1000,
  portRightBoundary: 2000,
  /* optional hostname where to start phantomjs server */
  host: '127.0.0.1'
