Hi, I would like to extract data from an excel sheet that contains multiple worksheets (and all of them containing some data). Since my excel sheet can have almost 30,000 records, I heard that using the Event-based API would improve the performance substantially, when compared to the normal HSSF APIs.
The main-content that I want to extract is present in only one of the many worksheets of the excel document and I'm not able to find a way to selectively extract the data from the worksheet of my interest. Or looking at it from another angle, I'm not able to figure out how to skip all the unwanted worksheets and process only the required worksheet. First, is it possible to solve the above mentioned problem in any way using the event-based API? If yes, then how:-) ? Second, considering the amount of records (approx 30000 rows and 20 columns) in my excel doc, am I right in assuming that using the Event based API will bring in a huge amount of performance benefits? I'm aware that my problem can be solved using then normal HSSF APIs. But, it's the performance-effect that I'm unaware of due to which I would like to use the event-based API. Could someone please help me out with this? Thanks. Regards, Sundeep Sivaraman Bangalore. Please do not print this email unless it is absolutely necessary.
