Import Historical Records from Excel to Custom App -

-

i need bit of help. company has data in multiple excel sheets. sheets straight forward (in map data types). of them merged rows , cells etc within 1 header. developing application in c# maintaining massive database proper user , role management , multiple departments stake holders.

i have identified relations within excel sheets , well. cannot understand how import historical data map data tables? basically, when new custom system designed, how import senseless data within it?

the thing think of writing utility program reads every row , every cell of excel sheets , extract required values insert proper database table. take ages due numerous number of excel sheets.

wondering of went through same thing have?how did or handle this?

many guys :)

if data not regular, you've got world of pain ahead of you. object model in excel can driven of windows scripting host languages, vbscript , jscript. in fact, scripting languages have support excel traversal.

however, you've noted, data layout isn't same across spreadsheets. had similar problem years ago traversing scada data power stations: each station did differently , changed format time time.
