Compare columns in Excel or CSV files with VLOOKUP

How to compare columns on the Excel sheet using VLOOKUP command
In short VLOOKUP command on the xlCompare.com checks for the presence of the value from FILE2 in the FILE1.
Use this command when you need to compare only two (or more) columns for matching values, without comparing other cells in the worksheets.
Data you are working with can be different structure in the FILE1 and FILE2.
  • VLOOKUP command in xlCompare works similar to VLOOKUP worksheet function in Excel. But there is a significant difference, VLOOKUP searches for a single value, while our service can search other worksheet for a combination of values.
  • FILE1 is treated as vocabulary.
  • FILE2 is treated as data file.
  • xlCompare gets values from the selected columns in the FILE2 and searches for these values in the selected columns in FILE1.
  • Rows with values, that are not present in FILE1 are marked with red color in the result panel.
  • Cells in the other columns are not compared.
  • VLOOKUP command compares only cells in the selected columns!
IMPORTANT: to use VLOOKUP command you need to select columns on both worksheets.
Look into next topic to get instructions on how to select columns for the VLOOKUP command.
Example of using VLOOKUP command
You have list of valid SKU#, you are working with, and you need to check if all records in the received Excel table contain valid SKU# values.
VLOOKUP command is an ideal solution for this case.
xlCompare uses same procedure for selecting Primary Key columns for the worksheet comparison and columns for the VLOOKUP function.
Use a key marker in the heading of the every column on the worksheet:
KEY
A
Click on the Marker to select this column for the VLOOKUP command
xlCompare highlights marker to reflect it's key state:
KEY
A
In addition to marker, xlCompare highlights data cells in the Primary Key column with color.
How to clear the marker state?
Second click on the marker clears it's state. Marker works like a switch.
Show I use Heading Rows with VLOOKUP command?
This is optional, but better to select heading rows to exclude heading area from the comparison.
This should make comparison results more accurate.

  1. Open your Excel files on this web page
  2. Select columns to be compared by clicking on the heading. Columns can be compared only when you selecte them!
  3. Compare two selected Excel sheets with VLOOKUP button
  4. xlCompare.com highlights missing values with red color
  5. Select the Filter option to get only missing or matching rows.
  6. Export this table into Excel by using Copy button.
VLOOKUP gives you values that are present and not present in the FILE1.
But how to find values that are present in the vocabulary (FILE1) and not present in the data file?
Switch FILE1 and FILE2, select same columns and apply VLOOKUP once again.
All you need to do is to switch vocabulary and data. This is very easy method to get the results.
Yes, both commands are applicable with the VLOOKUP function.
Filter has simplified options - it allows to show unique and equal values.
When you compare two columns there are no updated cells - only equal and added.
Copy command works exactly the same as in the Compare Tables command. It copies difference report into the clipboard.

How to pull data into other Excel file

How to export comparison report into XLSX file and save on disk?
