Introduction

xlnt is a modern C++ library for manipulating spreadsheets in memory and reading/writing them from/to XLSX files as described in ECMA 376 4th edition. xlnt is currently under active feature development and is on track for the version 1.0 release in the next few weeks. Until then, the API could have significant changes. For a high-level summary of what you can do with this library, see the feature list.

Example

Including xlnt in your project, creating a new spreadsheet, and saving it as "example.xlsx"

#include <xlnt/xlnt.hpp>

int main()
{
    xlnt::workbook wb;
    xlnt::worksheet ws = wb.active_sheet();
    ws.cell("A1").value(5);
    ws.cell("B2").value("string data");
    ws.cell("C3").formula("=RAND()");
    ws.merge_cells("C3:C4");
    ws.freeze_panes("B2");
    wb.save("example.xlsx");
    return 0;
}
// compile with -std=c++14 -Ixlnt/include -Lxlnt/lib -lxlnt
