This video demonstrates how to find all matching values between two columns in LibreOffice Calc. Precisely, in this video, we fill in columns A and B with random integer values between the numbers 1 and 100 (inclusive). The formula to generate the random values was the following:

=RANDBETWEEN(1;100)

After we filled in columns A and B with random values, we used the following formula in each cell of column C to find all common values between the first two columns:

=IF(ISERROR(MATCH(B1;A:A;0));"";B1)

## LibreOffice Cal commands used in this video

`RANDBETWEEN(Bottom; Top)`

– Returns an integer random number in a specified range.`IF(Test; ThenValue; OtherwiseValue)`

– Specifies a logical test to be performed.`ISERROR(Value)`

– Tests for error conditions, including the #N/A error value, and returns TRUE or FALSE.`MATCH(SearchCriterion; LookupArray; Type)`

– Returns the relative position of an item in an array that matches a specified value. The function returns the position of the value found in the lookup_array as a number.
