vlookup

I've got a spreadsheet of about 5000 user events associated with IPs, and I'm trying to use IP to determine location using just an Excel formula. The IPs in my log are structured as "dotted quads" (decimal notation). I figured VLOOKUP is the way to go here, so I downloaded WEBNet77's IPV4 IpToCountry database , which seems like a comprehensive and up-to-date resource (is there a better resource out there for this purpose?). The database includes about 140K rows of IP ranges, with the sheet structured like so: Colum labels A - G are, respectively: IP FROM, IP TO, REGISTRY, ASSIGNED, CTRY, CNTRY

Is there a way to inner join two different Excel spreadsheets using VLOOKUP? In SQL, I would do it this way: SELECT id, name FROM Sheet1 INNER JOIN Sheet2 ON Sheet1.id = Sheet2.id; Sheet1: +----+------+ | ID | Name | +----+------+ | 1 | A | | 2 | B | | 3 | C | | 4 | D | +----+------+ Sheet2: +----+-----+ | ID | Age | +----+-----+ | 1 | 20 | | 2 | 21 | | 4 | 22 | +----+-----+ And the result would be: +----+------+ | ID | Name | +----+------+ | 1 | A | | 2 | B | | 4 | D | +----+------+ How can I do this in VLOOKUP? Or is there a better way to do this besides VLOOKUP? Thanks. First lets get a

I have multiple spreadsheets in a workbook and I would like the following in basic English talk: IF worksheet1(cell)A3 , appears in 'worksheet2' column B - count how many times it appears in column b 'worksheet 2' So in other words - Lets say A3 = BOB smith - in work sheet 1 and appears 4 times in worksheet 2 - I want the formula to count the fact that A3 'Bob smith' is in worksheet 2 4 times, and come back and tell me 4. I have attempted to do separate calculations - with use of Vlookups - then in another cell to count/do if statement for example =COUNTIF(VLOOKUP(A9,'To retire'!J:J,9,1)) =IF

I would like to use a VLOOKUP function referring to a data table placed in a different sheet from the one where the VLOOKUP function in written. Example: in Sheet 1, cell AA3 I would like to insert the VLOOKUP function. I want the function to check the number in cell M3, find the same number in Sheet 2 range address A2:Q47 first column, and reproduce the value in the 13th column of that table. I've written this function but it reports #N/A as a result: =VLOOKUP(M3,Sheet1!$A$2:$Q$47,13,FALSE) One of the common problems with VLOOKUP is "data mismatch" where #N/A is returned because a numeric

This question already has an answer here: How to do vlookup and fill down (like in Excel) in R? 8 answers I have looked pretty much everywhere and cannot find the answer to this; R equivalent of VLOOKUP on Excel. VLOOKUP allows me to look up for a specific value throughout a column and apply it to each row of my data frame. In this case I want to find the country a particular city is in (from a database) and return the name of the country in a new column. So I have this database: countries <- c("UK", "US", "RUS") cities <- c("LDN", "NY", "MOSC") db <- cbind(countries, cities) db countries
