  • use-openssl-md5: Use OpenSSL implementation of md5 function. (See upstream document to learn more).
  • system-zlib: Use system zlib instead of included zlib.

Build requirements

How to build on windows

  1. Install Visual Studio
  2. Install LLVM
  3. Set environment variable LIBCLANG_PATH as C:\Program Files\LLVM\bin
  4. Run build

Example

Result Image

let workbook = Workbook::new("simple1.xlsx")?;

let mut sheet1 = workbook.add_worksheet(None)?;
sheet1.write_string(0, 0, "Red text", Some(&Format::new().set_font_color(FormatColor::Red)))?;
sheet1.write_number(0, 1, 20., None)?;
sheet1.write_formula_num(1, 0, "=10+B1", None, 30.)?;
sheet1.write_url(
    1,
    1,
    "https://github.com/informationsea/xlsxwriter-rs",
    Some(&Format::new().set_font_color(FormatColor::Blue).set_underline(FormatUnderline::Single)),
)?;
sheet1.merge_range(2, 0, 3, 2, "Hello, world", Some(
    &Format::new().set_font_color(FormatColor::Green).set_align(FormatAlignment::CenterAcross)
                  .set_vertical_align(FormatVerticalAlignment::VerticalCenter)))?;

sheet1.set_selection(1, 0, 1, 2);
sheet1.set_tab_color(FormatColor::Cyan);
workbook.close()?;

Run Example with Cargo

You can explore this example locally following the steps below:

  1. Install LLVM and set LIBCLANG_PATH if you are using windows. (see bindgen doc for details)
  2. clone or fork this repository
  3. git submodule update --init --recursive
    • The above command downloads the required C library so we can compile
  4. cargo run --example hello_spreadsheet

You should then see the example in target/simple1.xlsx. Enjoy!
