Conversation: reading an excel file in C?
Subject: reading an excel file in C?
Hi All,
I want to know,How can one read an Excel file into C,cell by cell?
Further I want to compare 2 excel files,cell by cell.
I know a crude way which is not working.
I can open an xls file and read it character by character untill a
'\t'(TAB).Then again read it char by char.
I think this should work since an Excel file is nothing but a tab
seperated strings.Am I correct?
What can be an elegant way?
Thanks,
-Siliconwafer
Only if the file is saved as an CSV file, with TAB delimiters.
Otherwise it could be quotes and commas seperating cells, again
if it's a CSV.
If it's an XLS, then you need to find the file format.

Which is proprietary, of course. And no C stuff, anyway.
Hint: googling for "WorkbooksP tr" could help ...

a dozen worksheets (all packed with endless rows of formulas) long, i

I've just discovered a bug in some code I wrote a little while ago, and I
need you guys' help to fix it.
My program imports data from a standard Excel Spreadsheet (just with
specific column headers). I used ODBC in my VB.NET program to read that
spreadsheet into a dataset, to make it easy to manipulate. The code I use to
read it is as the bottom of this posting.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
