If there are a lot of cell styles in MS 2007 .xlsx file, when loading the file in Aoo, it will take about 20 seconds to create the cell styles.
After analyze the sample file, there are lots of duplicated cell style items in the original file,and such file maybe created by script or other tools. So a method must be used to get rid of the duplicated unused cell styles.
In MS 2007 .xlsx file,there are 3 items to record the cell style.
- cellStyle
- cellStyles
- cellStyleXfs
Here is the result data by the rational purify.
