Re: [fpc-pascal] read cells contents from .xls file
Thanks for all suggestions. IMO fpspread...pas is too complex for & I'd need to hack thro' thousands of lines - maybe a simple program to read xls into csv, as in b) below could be added?. Here, fyi, In looking around I came up with these 2 : a) googled 'read xls' http://exceldatareader.codeplex.com/ Unfortunately I don't use c# but the mechanisms for reading spread look simple in the referenced page ie 1 line! Guess one could try to use the excel.dll in te reference in fpc & then access it from fpc b) using a <10 line vbs program referenced here to create a csv file then getting the data from that http://stackoverflow.com/questions/1858195/convert-xls-to-csv-on-command-line This is the way I'm doing it, running the vbs file from cmd using exec etc, simple if crude!. john On 1 October 2013 12:15, John Lee wrote: > Thanks - as you say (with nice irony) it isn't a simple format, and I > don't pretend to understand it, indeed it is 'doing my head in' - but I > don't want to write .xls or do charts etc, just read some cells (only in in > excel 2003, seems to be v11 according to help) - maybe my hope of a few > lines, with one or two units 'used', isn't possible but there seem to be > millions of lines here.

Re: [fpc-pascal] read cells contents from .xls file
Thanks - as you say (with nice irony) it isn't a simple format, and I don't pretend to understand it, indeed it is 'doing my head in' - but I don't want to write .xls or do charts etc, just read some cells (only in in excel 2003, seems to be v11 according to help) - maybe my hope of a few lines, with one or two units 'used', isn't possible but there seem to be millions of lines here. Is there an example of reading cells from named spread that you could point to?

Re: [fpc-pascal] read cells contents from .xls file
The source code of fpspreadsheet is open ... just copy/paste/modifiy it for your needs: https://sourceforge.net/p/lazarus-ccr/svn/HEAD/tree/components/fpspreadsheet/xlsbiff8.pas#l50 But BIFF8 is not a simple format, there is no simple answer to your question. It is encapsulated in a OLE Document storage system to start with, which is something pretty complex. BIFF2 till BIFF5 (Excel 5.0) were simple formats, but that's not the format you are looking for from your question.

Re: [fpc-pascal] read cells contents from .xls file
Thanks - that looks excellent, but the 'uses' list for this, for non lazarus users, has, I guess, lots of things in it. The problem is also that I'm trying to implement this hack in an old version of pascal, v2.2.2 for which I only have the compiler & basic rtl stuff - that's why I'd just like some info for a quick hack eg some bullets or some idea what I need to do eg to read the no or string in eg cell x23 of sheet jim in fred.xls.
