Re: [fpc-pascal] Re: read cells contents from .xls file
I didn't _want_ to use 3rd part products - I didn't really have any choice if I wanted to get something working in a finite time, given the 1000s of lines of code to try to hack, then test when I don't really understand them the fact that there isn't any easy fpc solution. Thanks all for you help. John On 2 October 2013 09:44, Reinier Olislagers reinierolislag...@gmail.comwrote: On 01/10/2013 21:44, John Lee wrote: Thanks for all suggestions.

Re: [fpc-pascal] Re: read cells contents from .xls file
I have it and use it - but not lazarus. But using some legacy 2.2.2 libraries w/o source want it to work there. Even with latest fpc it didn't seem very easy to get sheet data into csv, I couldn't follow the examples in fpspread..., seemed to need lots of lazarus stuff n units that I didn't understand, just to do something simple, as in my original email.

Re: [fpc-pascal] Re: read cells contents from .xls file
It's really very simple. fpspreadsheet requires lazutils, which comes inside the source code from Lazarus and lazutils does not require anything out of FPC. So if you don't want to use Lazarus, which would automatically solve the problem, then just pass 2 unit search paths to FPC when compiling your project which uses fpspreadsheet: 1 Path to fpspreadsheet 2 Path to lazutils (located in the folder lazarus/components/lazutils) You need to download Lazarus to have lazutils, but you don't have to use it as an IDE.

Is there an example of reading cells from named spread that you could point to? In case you hadn't found it: examples here http://wiki.lazarus.freepascal.org/FPSpreadsheet Excel 2003 .xls format is AFAIU BIFF8 as well. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
