We are using SharePoint 2010. I have permission (full access) on my site. I have three uploaded files (one Word .doc, one Excel .xls, one CSV .csv).

I had no problems editing Word and Excel files. But I could not edit CSV file. Even "Edit Document" button on CSV file was disabled (greyed off). The file is a read-only file.

Could anyone help me on this issue? Why does CSV file have difference behavior from other file formats in SharePoint? I tried to search but could not find anything from the web.

This question came from our site for professional and enthusiast programmers.

Add the following to DOCICON.XML (default location is C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\XML)

<Mapping Key="csv" Value="icxltx.png" OpenControl=""/>

Then in IIS Manager select the server and then select MIME Types, update the entry for csv to 'application/'.

This will allow you to click the file name link and have the file open in Excel however the edit document button will still be disabled.

Thanks quila Sands! How can I make the Edit Document enabled for CSV file? Any suggestions? Thanks a lot. YK – user9512 Jul 17 '12 at 18:22
@Yan. That will require some custom development to create an OpenDocuments control that knows how to handle a csv file. You could then specify this control in the OpenControl attribute of the Mapping XML element. This blog post has more info and a project that can provide a starting point. – Aquila Sands Jul 18 '12 at 9:50
Thank you very much Aquila Sands! After copy over xls's mapping then change xls to csv: <Mapping Key="csv" Value="icxltx.png" OpenControl="SharePoint.OpenDocuments"/>. CSV files now are editable from SharePoint. Issue resolved! – user9512 Jul 18 '12 at 20:15
