if you import the data (or append) regulary then turn the import into a table (select a cell within the data an click 'Insert', 'Table').Then create both columns (with the formulas) at the right end.<br />
The table will auto adjust and when you import the next time (and there are more or less lines) the formulas will adjust automatically.

<div class="content wysiwyg-content">
I have got a worksheet full of data (around 2000 rows and 15 columns). I need to do a sumif to see how often in the data, 2 columns match, to see how many rows have those same 2 values in these 2 columns (reference and address line 1). Can anyone provide any pointers, say for example column A is my &quot;count&quot; column, where I will be applying the SUMIF calculation to get a count, and column B is the reference column, and column C is the address line 1 column. <br />
<br />
e.g.<br />
count-reference-address1<br />
--------------------------<wbr />----------<wbr />---<br />
2-12345-1 EE street<br />
2-12345-1 EE street<br />

I need to do a sumif to see how often in the data, 2 columns match, to see how many rows have those same 2 values in these 2 columns (reference and address line 1). Can anyone provide any pointers, say for example column A is my "count" column, where I will be applying the SUMIF calculation to get a count, and column B is the reference column, and column C is the address line 1 column.
