rust_xlsxwriter 0.51.0

A Rust library for writing Excel 2007 xlsx files
Documentation

rust_xlsxwriter

The rust_xlsxwriter library is a Rust library for writing Excel files in the xlsx format.

The rust_xlsxwriter library can be used to write text, numbers, dates and formulas to multiple worksheets in a new Excel 2007+ xlsx file. It has a focus on performance and on fidelity with the file format created by Excel. It cannot be used to modify an existing file.

Example

Sample code to generate the Excel file shown above.

use rust_xlsxwriter::*;

fn main() -> Result<(), XlsxError> {
    // Create a new Excel file object.
    let mut workbook = Workbook::new();

    // Create some formats to use in the worksheet.
    let bold_format = Format::new().set_bold();
    let decimal_format = Format::new().set_num_format("0.000");
    let date_format = Format::new().set_num_format("yyyy-mm-dd");
    let merge_format = Format::new()
        .set_border(FormatBorder::Thin)
        .set_align(FormatAlign::Center);

    // Add a worksheet to the workbook.
    let worksheet = workbook.add_worksheet();

    // Set the column width for clarity.
    worksheet.set_column_width(0, 22)?;

    // Write a string without formatting.
    worksheet.write(0, 0, "Hello")?;

    // Write a string with the bold format defined above.
    worksheet.write_with_format(1, 0, "World", &bold_format)?;

    // Write some numbers.
    worksheet.write(2, 0, 1)?;
    worksheet.write(3, 0, 2.34)?;

    // Write a number with formatting.
    worksheet.write_with_format(4, 0, 3.00, &decimal_format)?;

    // Write a formula.
    worksheet.write(5, 0, Formula::new("=SIN(PI()/4)"))?;

    // Write a date.
    let date = ExcelDateTime::from_ymd(2023, 1, 25)?;
    worksheet.write_with_format(6, 0, &date, &date_format)?;

    // Write some links.
    worksheet.write(7, 0, Url::new("https://www.rust-lang.org"))?;
    worksheet.write(8, 0, Url::new("https://www.rust-lang.org").set_text("Rust"))?;

    // Write some merged cells.
    worksheet.merge_range(9, 0, 9, 1, "Merged cells", &merge_format)?;

    // Insert an image.
    let image = Image::new("examples/rust_logo.png")?;
    worksheet.insert_image(1, 2, &image)?;

    // Save the file to disk.
    workbook.save("demo.xlsx")?;

rust_xlsxwriter is a port of the XlsxWriter Python module by the same author. Feature porting is a work in progress. The currently supported features are:

  • Support for writing all basic Excel data types.
  • Full cell formatting support.
  • Formula support, including new Excel 365 dynamic functions.
  • Charts.
  • Hyperlink support.
  • Page/Printing Setup support.
  • Merged ranges.
  • Worksheet PNG/JPEG/GIF/BMP images.
  • Rich multi-format strings.
  • Defined names.
  • Autofilters.
  • Worksheet Tables.

rust_xlsxwriter is under active development and new features will be added frequently.

Features

  • default: Includes all the standard functionality. Has dependencies on zip, regex and lazy_static.

  • chrono: Adds supports for Chrono date/time types to the API. This is off by default.

  • zlib: Adds dependency on zlib and a C compiler. This includes the same features as default but is 1.5x faster for large files.

  • polars: Add support for mapping between PolarsError and rust_xlsxwriter::XlsxError to make code that handles both types of error easier to write.

  • wasm: Adds dependency on js-sys and wasm-bindgen to allow compilation for wasm/JavaScript targets.

  • test-resave: Developer only testing feature.

Release notes

Recent changes:

  • Added chart trendlines and gradient fills.
  • Added custom functions to table totals.
  • Added Wasm and Polars feature flags for compatibility.
