How to detect merged cells in excel with openpyxl : <p>I'm trying to read data from excel sheet that contains merged cells.
When reading merged cells with openpyxl the first merged cell contain the value and the rest of the cells are empty.</p>

<p>I would like to know about each cell if it merge and how many cells are merged but I couldn't find any function that do so. 
The sheet have empty others cells, so I can't use that.</p>

<p>Will appreciate any help, I prefer openpyxl module but other modules can work,too.</p>

<p>Thank you all! </p>
