Still problems in XLS-files with sums formulas. lazarus / 49-FPSpreadsheet ---------------------------------------------------------------------- Soner · 2018-08-16 10:57 Still problems in XLS-files with sum formulas. I created the workbook in zip-file with lazarus program and saved it as xls-file. Then I opened it in Excel Xp and wrote in the cell "I10" 10 and saved it. Now when I open this file with my program or spready then in the cells  H41-N41 are no sum-formulas. But in the cell I49 is sum-formula visible. I create al the sum-formulas with the same code: (with different column and row numbers) Code: Pascal  [Select][+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i aSh.WriteFo rmula(r,c,'=SUM(N'+roZeit+1).ToString+':N'+arsum.ToString+')');    aSh.WriteNumberFormat(r,c,nfFixed,2); Zip contains second file with the name "Stundenplan-2018-8-test- cut.xls". I created this file form the first to make it easy debugable(deleted some cells and rows in Excel xp). But Spready shows  sum-formulas from this file. ---------------------------------------------------------------------- wp · 2018-08-16 13:21 Try ccr-r6604. Looks as if the BIFF reader did not read the token for relative cell ranges correctly. ---------------------------------------------------------------------- Soner · 2018-08-16 17:33 Thanks.
