Question

I have two tables:

# BILLING PERIOD TABLE
+-----------+
| id | value|
-------------
|  1 | some |
|  2 | else |
xxxxxxxxxxxxx

and

# ELECTRICITY TABLE

+----------------------------+
| billing period| value      |
------------------------------
| 1             | desired val|
| 2             |            |
| 3             |            |

And I would like to write formula that takes and compares billing period id with billing period and puts value from billing period table to the cell value next to billing period

any help will be appreciated

Answer 1

As was suggested by @Tim Williams, VLOOKUP() is the way to go.

Assuming you’ve named the first table BILLING_PERIOD, and the second table ELEC, and using your headers, in the value column you would use:

=VLOOKUP([@[billing period]],BILLING_PERIOD,2,FALSE)

An extra touch can be to surround it with IFERROR, to insert some default value if the id isn’t in the table, instead of showing a #N/A error.

EDIT: just noticed that it wasn’t mentioned, but my assumption was that you are talking about two excel tables, if that was not the meaning, please be more specific.
