After you have exported sources fromone agent (for more, follow this link) or from multiple agents (follow this link to find out how to do this) you may want to edit the file either by deleting sources or adding new ones to the list. When you open the excel file you may find that Digimind no longer recognises the information inside. This problem is easy to rectify, following the steps below.
Save the file in the correct format
Windows 7 and Older
Save the file in .htm format, as a Web Page. This is usually the default option and also it is in your list of choices from the drop-down menu.
Then, further down the page, select to save only that sheet.
If you are working on a computer using Windows 8, select to save the document as a Web Page, and save only that sheet:
Modify the file extension
You will now see the file as .htm
Right click on the file and rename it with .xls at the end.
Import the file to your agent
You can now use this file to upload the sources to your agent.
