Hi all,
I want to insert in a already excel sheet i have been able to find codes for creating new workbook and then writing data to it even reading is easy but i could not find the code to insert data in a existing excel.Please post your thoughts and solutions
Thanks
And i m using Jexcel API's
I just had this problem with a program that I just wrote. The easiest way i found is to have 2 excel files. You need 2 because you need one be read and then one so the program thinks its creating a new writable one, because you get non compatible errors if you do not. When the program opens get all the info from the regular workbook and populate it into a 2 dimensional array. Then have the program do its thing, and store new data to the array. After that have a save button or something, or however you want to export the workbook. Populate the writable workbook sheet with the array, then (here's the key) before you *.write and *.close set the output file to the readable regular excel file name you used to populate the array at the beginning. I hope that makes sense, the syntax is "yourWorkbook.setOutputFile(The string of the readable excel file name);". Hope that helps let me know if you have questions
I am also having the same problem.... I will be grateful to you if you can post some code to do this...Quote:

As you can see ImportExcel.book is my file name from the original imported excel file that way is always saves and reads the same one. This is also useful for data storage.
Hope this helps, more spec questions would be nice too. ThanksQuote:
