Rust Requires Chilkat v11.3.0+

XLSX Convert Sheet to CSV

Open an Excel spreadsheet (.xlsx) and loads a sheet into a CSV object. Rust

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// .xlsx files are Zip archives
let zip = chilkat::Zip::new();
if zip.open_zip("qa_data/excel/fakeCompanies.xlsx").is_err() {
    println!("{}", zip.last_error_text());
    return;
}

let csv = chilkat::Csv::new();
let sheet_names = chilkat::StringTable::new();
if csv.xlsx_get_sheets(&zip, &sheet_names).is_err() {
    println!("{}", csv.last_error_text());
    return;
}

if sheet_names.count() == 0 {
    println!("There are no sheets in the .xlsx");
    return;
}

// Get the name of the 1st sheet.
let sheet_name = sheet_names.string_at(0).unwrap_or_default();

// Load the 1st sheet into the CSV.
// We could've also loaded the 1st sheet by passing an empty string for the sheet name.
if csv.xlsx_load_sheet(&zip, &sheet_name).is_err() {
    println!("{}", zip.last_error_text());
    return;
}

// The Chilkat CSV API can now be used to read, modify, or insert cells.
// ...
// ...

let csv_str = csv.save_to_string().unwrap_or_default();
println!("{}", csv_str);

// Sample output:
// CompanyName,Address,City,State,Zip,Phone
// Acme Innovations LLC,7428 Westbrook Blvd,Oak Bend,IL,60514,630-555-2398
// BlueHorizon Data Systems,1850 Crestline Park Suite 210,Rivergate,CA,92814,714-555-8821
// Pinnacle Manufacturing Corp,3912 Industrial Loop,Maple Ridge,TX,77301,281-555-4477
// Evergreen Analytics Inc,1250 Highland Terrace,Stonefield,WA,98290,425-555-9914
// NovaTech Solutions Group,578 Marketview Drive,Clearwater,FL,33760,727-555-6032

// Save to a .csv file.
if csv.save_file2("c:/temp/qa_output/fakeCompanies.csv", "utf-8").is_err() {
    println!("{}", csv.last_error_text());
    return;
