Reading an excel

Question

Hi all,
We have many methods to read an excel sheet…
A. Save it as .csv & read as file (but coding is too much
& if you cell have any comma separated value it cause a
problem)
B. Create ODBC & than DSN inside of CF admin (it is also
painful if you want to read different type of excel.)
C. There is some paid custom tag available on net (you need
to pay much amount & some limitations are there)
D. Last & final method is use Jakarta POI (some already
guess about it)
I use Jakarta POI…the problem is that with these POI
that there is not enough material or documentation is available on
net…I am lucky I did much R &D & get the solution.
With using these POI our most of requirement’s get
fulfill…see the sample code to read an excel sheet without
creating a DSN
<cfset fileIn =
createObject("java","java.io.FileInputStream").init("#file_url#")/>
<cfset wb =
createObject("java","org.apache.poi.hssf.usermodel.HSSFWorkbook").init("#fileIn#")/>
<cfset sheet = wb.getSheetAt(0)/> //this is sheet
number you can read multiple sheet..
<cfset Last_Row = sheet.getLastRowNum()>// you will get
number of last row to validate number of row
<cfloop index="i" from="1" to="#Last_Row#">
<cfset row = sheet.getRow(javacast("int",#i#))>
<cfloop index="j" from="0" to="18">
<cfoutput>
<cfset Cell_len=#len(row.getCell(javacast("int",j)))#>
<cfif #Cell_len# GT 0>//to validate null value(blank
cell)
<cfset cell_Add=row.getCell(javacast("int",j))>
<cfset "c#j#"=cell_Add.getNumericCellValue()>// to
read numenric value
<cfset "c#j#"=cell_Add.getStringCellValue()>// to read
string value
<cfelse>
<cfset "c#j#"="NULL">
</cfif>
</cfoutput>
</cfloop>
</cfloop>
Now a tip: use CFdump for wb, sheet, row you will able to see
all related function.
I hope this small description will provide you enough
help…if any one have any question feel free to contact
me…
Thanks & Regards

Yes Prabhdeep,
I am able to read the excel and generate the xml. Please find below the instance of xml having 4 records.
It has a header and details section. Under details, we can see the values of "Milestone 1" and "Milestone 2" for "Milestone" column in the excel.
<ns0:Test xmlns:ns0="Test Namespace">
<Header>
<BLAWBNumber>XYZ</BLAWBNumber>
<Container>123</Container>
<TransportationType>Land</TransportationType>
<Details>
<Detail>
<Milestone>Milestone 1</Milestone>
<Country>US</Country>
<City>Laredo, TX</City>
<EventDate>2014-02-26T00:00:00</EventDate>
</Detail>
<Detail>
<Milestone>Milestone 1</Milestone>
<Country>US</Country>
<City>Laredo, TX</City>
<EventDate>2014-02-26T00:00:00</EventDate>
</Detail>
<Detail>
<Milestone>Milestone 2</Milestone>
<Country>US</Country>
<City>Laredo, TX</City>
<EventDate>2014-02-26T00:00:00</EventDate>
</Detail>
<Detail>
<Milestone>Milestone 2</Milestone>
<Country>US</Country>
<City>Laredo, TX</City>
<EventDate>2014-02-26T00:00:00</EventDate>
</Detail>
</Details>
</Header>
</ns0:Test>
The requirement is,
The records having "Milestone 1" should be mapped to EDI 214 and the records with "Milestone 2" as milestone value should be mapped to EDI 315 output.
Please suggest on the same.
Thanks.
Anand
