Imagine, you have these two tables:
Sample worksheet 1
Sample worksheet 2

2. Select Key Columns and Heading Rows

In general this step is optional, but it is required if your worksheet has table (database) structure. If you are working with CSV file or data, that was exported from database - it is required.
Key Columns are used to identify if two rows represent same record in table. xlCompare.com allows to select several key columns at once.
Heading Row usually defines header of the table and contains names of the database table.
In our example, column ID identifies record in this table. So, it should be used as Key Column. EMAIL column can also be used as Key, as it identifies every user. Columns like NAME, EMAIL, ADDRESS, TAX ID, SKU, PART NUMBER and similar - are typical examples of the Key Column.
Click on the
KEY
marker in the column heading to mark column as a key.
First row in this table contains field names - this is very common case. So, our header consists of 1 row only.
Click on the
HDR
marker in the row heading area to mark first row as header row.
Now our spreadsheets have following look:
Sample worksheet with heading and key column 1
Sample worksheet with heading and key column 2
Key column and heading row are highlighted with color. Data is ready for comparison.
