Dear VincentB,
Thanks for your inquiry.
Sorry that I am afraid that we can't give you the non-obfuscated version as it is confidential. Regarding to the issue, there is no signification progress towards it, just reduce several seconds currently. Since the document contains lots of data, Spire.Xls needs to entirely unfold the data, and then manipulate the data, so the process will take more time, the process should be different with Excel. We will optimize the process step by step, one more thing, it is difficult to optimize this part to arrive at times equivalent to Excel as different mechanism.
Thanks for your understanding.
Sincerely,
Betsy
