A JavaScript library enabling the use of the SharePoint 2007/2010 Datasheet view that was based on MS Access
The end user must have Microsoft's Access 2010 database engine (32-bit) installed (https://www.microsoft.com/en-us/download/details.aspx?id=13255) to support the ListNet / STSList.dll ActiveX component (https://msdn.microsoft.com/en-us/library/ms416795(v=office.14).aspx) The end user must use Microsoft Internet Explorer (32-bit) as their browser when trying to view legacy datasheets https://www.microsoft.com/en-us/download/internet-explorer.aspx
Upload both "spLDS_replaceQuickEditView.js" and "wp_spLDS_replaceQuickEditView.html" to your site's Style Library Go to a page on your site that contains one or more Quick Edit (SharePoint 2013 datasheet) views Edit the page, then add a Content Editor Web Part (CEWP) to the page Edit the Content Editor Web Part, and set its Link to point it to the "wp_spLDS_replaceQuickEditView.html" web part file you uploaded to your Style Library a moment ago Optionally, set the Chrome Type property (under 'Appearance') of the Content Editor Web Part to be "None" Click OK to save your changes to the Content Editor Web Part Stop editing the page to save your changes Once the page loads, you should see messages in your browser's script console about the code working to replace each Quick Edit view on the page with a legacy datasheet
A demo of how easy this is to implement is available on YouTube https://youtu.be/LPrTQkkymMI
NOTE!!! The old datasheet view's performance wasn't great. If you add this to a page containing more than 1 or 2 Quick Edit views, you should expect that the page performance and initial load time will be less than ideal.
