EDIT: I’ve created a JavaScript API for Sharepoint that handles the file creation. Just look at http://aymkdn.github.com/SharepointPlus/symbols/%24SP%28%29.html#.createFile
Did you know it’s possible to create a file from scratch and to add it into a shared documents library of Sharepoint, and only with Javascript ?
To do it we’ll use the « copy.asmx » web service with the « CopyIntoItems » function.
If you check http://your_sharepoint/_vti_bin/copy.asmx?op=CopyIntoItems you’ll see that we have several details about the « CopyIntoItems » function. Unfortunately it’s very difficult to find any information regarding this on the Web, and specially for Javascript…
So, here is the solution to create a file, e.g. an Excel file (.xls) with a regular HTML table, and we’re going to save it to this library: « http://your_sharepoint/Shared Documents/ » (Note: I’m using jQuery for the AJAX requests).
// The file content must be encoded into Base64. To do it I use the function available on my blog (http://blog.kodono.info/wordpress/2011/07/27/midi-code-encoder-decoder-en-base64-pour-javascript-programmation/)
function encode_b64(a,b,c,d,e,f){b="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";c='=';for(d=f='';e&=3,a.charAt(d++)||(b=';=',e);f+=b.charAt(63&c>>++e*2))c=c<<8|a.charCodeAt(d-=!e);return f}
// "Upload" is the name of our function to do the job
// txtContent is a plain text, the content of our file
// destinationUrl is the full path URL to the document library (with the filename included)
function Upload(txtContent, destinationUrl) {
var jsStream = encode_b64(txtContent);
var soapEnv = "<?xml version=\"1.0\" encoding=\"utf-8\"?>"
+"<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">"
+"<soap:Body>"
+"<CopyIntoItems xmlns=\"http://schemas.microsoft.com/sharepoint/soap/\">"
+"<SourceUrl>http://null</SourceUrl>"
+"<DestinationUrls><string>"+destinationUrl+"</string></DestinationUrls>"
+"<Fields><FieldInformation Type='File' /></Fields>"
+"<Stream>"+jsStream+"</Stream>"
+"</CopyIntoItems>"
+"</soap:Body>"
+"</soap:Envelope>";
jQuery.ajax({
url: "http://your_sharepoint/_vti_bin/copy.asmx",
type: "POST",
dataType: "xml",
data: soapEnv,
beforeSend: function(xhr) { xhr.setRequestHeader('SOAPAction', 'http://schemas.microsoft.com/sharepoint/soap/CopyIntoItems'); },
contentType: "text/xml; charset=\"utf-8\""
});
}
Upload("<html><table><tr><th>Colonne 1</th><th>Colonne B</th></tr><tr><td>Total:</td><td>1500</td></tr></table></html>","http://your_sharepoint/Shared Documents/test.xls");
Then, when you’ll click on the new « test.xls » file, your web browser will want to open it with Excel. MS Excel should show you a warning message, but just click YES and you’ll see your table inside the sheet !
Of course you can create any type of files (.txt, .jpg, .doc, …) and with any content.

It gives 400 – bad request
Since this article I’ve created a JavaScript library that permits to create a file : http://aymkdn.github.com/SharepointPlus/symbols/%24SP%28%29.html#.createFile
I’m going to update the blog post.
Got 400 – bad request too

Also check with Firebug or the web development toolbar to see the kind of response your receive. You certainly send the wrong information to the server.
