Scroll Through Each Cell Containing The Name Of A Workbook

I have a spreadsheet which contains about 800 rows. Each row contains a column with the name of a different workbook. I need to scroll through each cell containing the name of a workbook and open that workbook, extract two specific cell contents from each workbook opened, and paste that information into the two cells next to the original cell containing the workbook name.

Example:

Summary Workbook column C: contains names of workbooks.
For each workbook name, I need to open the respective workbook.
Then in the first tab of the workbook I need to extract the information in E6 and K7 and copy that information back into the summary workbook in the two cell to the right of column C.
