This is a part of data clean up series based upon the 10 rules for clean data. This video covers rules 1, 5, 6, 10 – cross-tabs, data growing horizontally and multi-layered headings.
We spend lot of time in data cleaning. But there is no simple definition of exactly what clean data means. Therefore, I created a simple 10 item checklist. If all 10 items are correct, data is clean. Simple and easy to use.

If a cell has no data in it, the data from the cell on the left side spills over it. This can lead to confusion while reading and understanding the data. How to remove this cell spill-over? Very simple. Just three steps:
- Select the data range.
- Press Ctrl G or F5 to open the Go To dialog.
- Click the Special button.
- Choose the Blanks option.
- Now, all the empty cells in the highlighted area will be selected.
- Just type a spacebar. This will go automatically into the active cell.
- DO NOT press ENTER. DO NOT disturb the selection.
- Press CTRL ENTER.
- That’s it. Now all the spill-over items will be truncated.
Excel Data Model is a database that is built-in to Excel. It has been around since 2010. Using it increases the capacity of Excel to handle millions of rows, it reduces file size significantly and eliminates VLOOKUP for code to description mapping. These new options in Excel 2016 and above simplify the usage of Excel Data Model and improve performance for large data operations. Go to File – Options – Data tab.
