XLSX ファイルの読み書きと編集を、Rust でも Python でも。

use crabxl::{CellAddress, CellValue, SaveOptions, WorkbookEditor, WorkbookReader};

fn main() -> crabxl::Result<()> {
    // Stream the cells that are present, row by row
    let mut workbook = WorkbookReader::open("input.xlsx")?;
    let mut rows = workbook.rows("Sheet1")?;
    while let Some(row) = rows.next_row()? {
        for cell in row.cells {
            println!("{:?}: {:?}", cell.address, cell.value);
        }
    }

    // Edit one value and keep everything else as it was
    let mut editor = WorkbookEditor::open("input.xlsx")?;
    editor.set_value("Sheet1", CellAddress::new(0, 0)?, CellValue::Integer(42))?;
    editor.save_path("output.xlsx", SaveOptions::default())?;
    Ok(())
}
