Lets say I have an excel sheet with 4 columns of data & 20,000 rows of data in each column. If this code doesn't do what you want, the only way to go back is to close without saving and reopen. There are a variety of options for connecting R to Excel, including From there, you can perform any number of statistical or graphing operations.What is the most efficient way to get it so that I have all of that data consolidated into one column (I. - 80,000 rows of data in column A instead of 20,000 rows of data spread out across 4 columns). What I mean is, if your solution isn't a "formula" but VBA, how do I implement that solution? If you use the RExcel plugin above, you can fire all of this up and run it within Excel itself.After you share a workbook, many of Excel's features can't be used.There's a list of unavailable features for Excel 2003 on the Microsoft site, and in Excel's help.This can be very tedious as there are over 300 lines to the original file.What I need is a VBA macro that will compare the two workbooks and highlight the differences and (ideally) update the workbook which is on my computer (It can either update the master workbook, or it can create a new workbook).You will need to modify the ranges in the COUNT function to match the maximum number of rows in the source sheet. If you need something other than a 0 for empty cells, you may prefer to include a conditional.A script to reformat the data may well be more efficient, but 20k rows is no longer a real limit in a modern Excel workbook. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).
After a few weeks you decide to compare both lists to make sure everyone on your friend’s list (List B) is also on your list (List A).
For example, you can't add any of the following features, and in some cases you can't even change the existing items: If you do need to create a shared workbook, check the list of restricted features, and make sure you have everything set up exactly the way you want it, before you share the file.
Test everything after you share the file, because things might not work the way they did before. Find out exactly what the workbook's purpose is, and why multiple people need to use it.
As I previously discussed, Excel provides many useful ways to automatically compare two lists of data or information.
In our other example we compared two lists of four digit account values; for this example we’ll compare two lists of names.
Occasionally a client asks me to create a shared workbook in Excel, so two or more employees can work in it at the same time.
