as3xls - Opensource library to read/write Excel files using Adobe Flex


In multiple Flex based RIA, it is necessary to import/export data in Excel format. Normally, this involves the use of a server side script. However, it is not not always possible and/or feasible to go for a client/server architecture to implement the same.

"as3xls" is an excellent opensource package to read and write Excel files in Flex and can be used in scenarios where server-side script cannot be used.  It support the use of text, number formula and dates (in read mode) and tex, number and date (in write mode) from Excel version 2.x - 2003.

There is a good cookbook entry to demonstrate the usage of the library at:
