Arguments
Return value
It returns a single column.
Example
Here we take the table below as an example to demonstrate the different uses of the TOCOL function.
#Example1: Transform a range to a single column and keep all values by default
For example, you want to take only the first three rows or columns from the sales table. You can apply one of the formulas below to get it done.
The range above contains both blanks and error values. To transform the range to a single column and keep all values in the resulting column, please apply the following formula.
Select a cell, such as H6 in this case, enter the following formula and press the Enter key to get the new column.
=TOCOL(B6:F9)
Notes:
#Example2: Transform a range to a single column and ignore certain types of values
To ignore all blanks, you just need to specify a number 1 for the ignore argument. The formula is as follows.
=TOCOL(B6:F9,1)
To ignore error values, specify the number 2 for the ignore argument. The formula is as follows.
=TOCOL(B6:F9,2)
To ignore both the blanks and errors, specify a number 3 for the ignore argument.
=TOCOL(B6:F9,3)
#Example3: Transform a range to a single column by scanning values by column
By default, the TOCOL function scans the array by rows. If you need to return a single column from the array scanned by column, you need to set the scan_by_column argument to TRUE.
Select a cell, say J6 in this case, enter the following formula and press the Enter key to get the new column.
=TOCOL(B6:F9,3,TRUE)
