# Lookup up cell values in Numbers

I want to build a simple word translator which may look like this:

• COLUMN A: I have a list of words, each on a row. (1:Airplane, 2:Car, 3:Cat, 4:Dog etc..)
• COLUMN B: I have a list of the same words in another language, each on a row. (1:Aereoplano, 2: Macchina, 3:Gatto, 4:Cane etc..)
• Then I have two cells. In the first one, I can type any word. The second cell is the formula that I want to create. The formula should:

• check if "my word"(the word that I type) is in the list of column A
• if it exists, it should return its adjacent word of the second column
• If no words match, the formula should not return anything.

I'm struggling with finding the correct functions to accomplish this, any pointers are welcome.

UPDATE I finally found the solution. Best solution for me is
`=IFERROR(VLOOKUP(B7;'Table 1-1'::B4:D53;3;FALSE);0)`

• @fsb If somebody doesn't know about `VLOOKUP` and friends, even the first step might be difficult. I wouldn't expect an answer to give a full solution but at least some indications on what to look for. Commented May 7, 2017 at 15:17
• After some researches, I found that the simple LOOKUP formula works perfectly for the purpose. Thanks for the help. Commented May 7, 2017 at 16:40
• @patrix I didn't see any indication that the OP made an attempt to find the solution. I know it's difficult to get the idea of `VLOOKUP` across in this type of Q&A setting (it's best learned via tutorial). I was trying to avoid a 'try this...' and then 'try this...' back-and-forth and was encouraging the OP to search for solutions first and then let us know what help is needed.

• If you got a solution, great. But please post it as an answer below (and upvote/accept it) so people will have it easier to find the solution in the future. Commented May 7, 2017 at 19:13

This answer to a related question explains how to use `VLOOKUP` in combination with `IFERROR`.

If `VLOOKUP` cannot find the `exact match`, then it throws an error. To catch this error, wrapping the formula in the `IFERROR` function allows the author to supply a default (in the OP's case, an empty string `""`) to display in the event of no match.

The following example uses a third table to display the translation. That table is then locked so as to protect the formula from being inadvertently overwritten. The words `NOT FOUND` are used here to show the error event.

If match is found:

No match:

From the documentation:

VLOOKUP(search-for, columns-range, return-column, close-match)

search-for: The value to find. search-value can contain any value.

columns-range: A collection of cells. columns-range must contain a reference to a single range of cells, which may contain any values.

return-column: A number value that specifies the relative column number of the cell from which to return the value. The leftmost column in the collection is column 1.

close-match: An optional modal value that determines whether an exact match is required.

close match (TRUE, 1, or omitted): If there’s no exact match, select the row with the largest left-column value that is less than or equal to the search value. If you use close match, you can’t use wildcards in search-for.

exact match (FALSE or 0): If there’s no exact match, returns an error. If you use exact match, you can use wildcards in search-for. You can use the wildcard ? (question mark) to represent one character, an * (asterisk) to represent multiple characters, and a ~ (tilde) to specify that the following character should be matched rather than used as a wildcard.

• Ah bjbk! I woke up this morning and I wanted to publish a complete explanation of the process... and you made this gem!! Thanks. That's exactly what I did and you represented in the clearest way. Thanks! Commented May 9, 2017 at 6:18
• Glad it helped! If it solves the problem pleas mark as answered for the benefit of others. Cheers!
