CD11c-YFP (Yellow Fluorescent Protein) mice allowed CD11c+ cell visualization. Contralateral PBS-treated eyes served as controls. Corneas were treated with gentamicin and ofloxacin (0.3%) or gentamicin alone, some also treated prior to lens wear (24 h). To test involvement of ocular-associated bacteria, the impact of topical antibiotics on corneal CD11c+ cell populations during 24 h of lens wear was examined.

Using VLOOKUP (which returned the serial number of records where there was a match, and #N/A for no match/new records) took just over 14 seconds, and for my requirements was actually quicker than using the conditional formatting method.Previously we reported contact lens-induced CD11c+ cell responses in healthy mouse corneas, a phenomenon that also occurs in humans. I had been using COUNTIF which was taking about 50 seconds to calculate.

The comparison I was doing was checking over 150,000 serial numbers on my "new data" file to see if they appeared in the "original data" file (any that did not appear needed the entire row, spanning about 40 columns of data, to be merged into the original). I had data in two separate files ("original data" and "new data"), and had to copy the records from one file to the other in order to do the comparison using the highlight duplicates approach.Ģ) If you have a lot of data, the large number of conditionally formatted cells can cause Excel to hang/crash. This trick works well, but has a couple of drawbacks.ġ) Both lists of data must be in the same workbook. Now I'm going to play with it some more and see if I can get this to work without having to merge the data into one spreadsheet. The color of the font also told me exactly which set of data had that row so that I could make sure I only added the right rows to the original spreadsheet. Next was to sort the data by cell color to group all the 'missing' rows together. I now had every row highlighted that was NOT in both files, regardless of which file it started in. Change Format all: to 'unique' Select a highlight color Click OK Now from the Home tab, select Conditional Formatting, 'New Rule', 'Format only unique or duplicate values'. that's right, 4 columns: date, invoice#, product, qty. Then I selected 4 columns to use for the comparison. You should now have one spreadsheet with two different colored rows - red ones from original spreadsheet, black ones from second spreadsheet. Then I selected all the rows in the second spreadsheet, copied them and pasted them at the end of the rows in the first spreadsheet. In the first spreadsheet I selected all the rows and changed the font to red. I had to find the rows in a second spreadsheet that were not in an original spreadsheet. Īfter seeing this and playing with it a bit, I was happy to discover that I could use this method to select multiple columns to compare. Spare a minute to become superawesome at work – Read a Quick Tip. Hats off to Artem for sharing this beautiful tip with us. See the screencast aside to see how this works ( click here for a detailed demo). Go to Conditional Formatting > Highlight Cells Rules > Duplicate Values.Select cells in both lists (select first list, then hold CTRL key and then select the second).A Ridiculously easy and fun way to compare 2 lists So here, I am documenting that technique so we all remember it and use it. I somehow missed this beautiful and dead-simple way to compare lists in Excel. I think it is sell “geeky”, but it gets job done very very quickly when you don’t want to mess around.Īrtem must be an Excel Yoda. Then in one list non-highlighted are values that are not present in the second list, and opposite for the second list.
The result is that it highlights in both lists the values that ARE the same.
The quickest way to find all about two lists is to select them both and them click on Conditional Formatting -> Highlight cells rules -> Duplicate Values (Excel 2007). Last week we discussed a fun and easy way to compare two lists of data in excel using conditional formatting.
