Hi ,

Kindly give me the code sample for excel to pdf conversion using Spire.Xls.

i wanted to show one sheet per page in pdf irrespective of no of fields in excel sheet.

for example if the single sheet has 150 fields , the converted file needs to show those 150 fields of sheet in single pdf page.

i couldnt able to upload the xlsx, xls in this topic .

so please create some sample excel file with more than 100 fields and do the conversion process.

kindly provide the sample code for the same.

based on the output , i can go for purchase the same by convincing my managements .

Already there is talk is happening for word to pdf conversion , i wanted to done the excel to pdf using same spire DLL

reply me ASAP

Regards,
Arafath

Hi there
I have encountered the same question with you recently.I usually convert pdf files using a pdf processing program.But it can not convert excel to pdf files.It can only convert pdf to png or some other image formats.So i want to get a new pdf converter.It's difficult for me to covnert pdf files using a code.Is there any method which can convert pdf directly?Thanks a lot.
