Usage

Installation

Add the following code to Cargo.toml

[dependencies]
umya-spreadsheet = "2.1.1"

# WebAssembly support
umya-spreadsheet = { version = "2.1.1", features = ["js"] }

# Use only png for image processing
umya-spreadsheet = { version = "2.1.1", features = ["image/png"] }

Add the following code to main.rs

extern crate umya_spreadsheet;

Read file

let path = std::path::Path::new("./tests/test_files/aaa.xlsx");
let mut book = umya_spreadsheet::reader::xlsx::read(path).unwrap();

Read file (Lazy)

Delays the loading of the worksheet until it is needed.
When loading a file with a large amount of data, response improvement can be expected.

let path = std::path::Path::new("./tests/test_files/aaa.xlsx");
let mut book = umya_spreadsheet::reader::xlsx::lazy_read(path).unwrap();

New file

let mut book = umya_spreadsheet::new_file();

Write file

let path = std::path::Path::new("./tests/result_files/bbb.xlsx");
let _ = umya_spreadsheet::writer::xlsx::write(&book, path);

Write file with password

let path = std::path::Path::new("./tests/result_files/bbb.xlsx");
let _ = umya_spreadsheet::writer::xlsx::write_with_password(&book, path, "password");

let from_path = std::path::Path::new("./tests/test_files/aaa.xlsx");
let to_path = std::path::Path::new("./tests/result_files/bbb.xlsx");
let _ = umya_spreadsheet::writer::xlsx::set_password(&from_path, &to_path, "password");

Read Value

let mut book = umya_spreadsheet::new_file();
book.get_sheet_by_name("Sheet1").unwrap().get_cell("A1").get_value();
book.get_sheet_by_name("Sheet1").unwrap().get_cell((1, 1)).get_value();
book.get_sheet_by_name("Sheet1").unwrap().get_cell((&1, &1)).get_value();
book.get_sheet_mut(0).unwrap().get_cell((&1, &1)).get_value();

Change Value

let mut book = umya_spreadsheet::new_file();
book.get_sheet_by_name_mut("Sheet1").unwrap().get_cell_mut("A1").set_value("TEST1");
book.get_sheet_mut(0).unwrap().get_cell_mut("A1").set_value("TEST2");

Move Values

let range = "A1:A3";
let row = 10;
let column = 2;
book.get_sheet_by_name_mut("Sheet1").unwrap().move_range(range, &row, &column);

Change Style

let mut book = umya_spreadsheet::new_file();
let mut style = book.get_sheet_by_name_mut("Sheet1").unwrap().get_style_mut("A1");
// fill color on red.
style.set_background_color(umya_spreadsheet::Color::COLOR_RED);

New Chart

let mut book = umya_spreadsheet::new_file();
// Add Chart
let mut from_marker = umya_spreadsheet::structs::drawing::spreadsheet::MarkerType::default();
from_marker.set_coordinate("C1");
let mut to_marker = umya_spreadsheet::structs::drawing::spreadsheet::MarkerType::default();
to_marker.set_coordinate("D11");
let area_chart_series_list = vec![
    "Sheet1!$A$1:$A$10",
    "Sheet1!$B$1:$B$10",
];
let mut chart = umya_spreadsheet::structs::Chart::default();
chart.new_chart(
    umya_spreadsheet::structs::ChartType::LineChart,
    from_marker,
    to_marker,
    area_chart_series_list,
);
book.get_sheet_by_name_mut("Sheet1").unwrap()
    .add_chart(chart);

Struct

Pass the book as a Spreadsheet to modify it in other functions.

let mut book = umya_spreadsheet::new_file();
let _ = book.new_sheet("Sheet2");
update_excel(&mut book);

fn update_excel(book: &mut Spreadsheet) {
   book.get_sheet_by_name_mut("Sheet2").unwrap().get_cell_mut("A1").set_value("Test"); 
}

See the next chapter for implementation status and more detailed usage.
