Swift Requires Chilkat v11.3.0+

XLSX Convert Sheet to CSV

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

func chilkatTest() {
    var success: Bool = false

    //  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 = CkoZip()!
    success = zip.open(zipPath: "qa_data/excel/fakeCompanies.xlsx")
    if success == false {
        print("\(zip.lastErrorText!)")
        return
    }

    let csv = CkoCsv()!
    let sheetNames = CkoStringTable()!
    success = csv.xlsxGetSheets(xlsx: zip, sheetNames: sheetNames)
    if success == false {
        print("\(csv.lastErrorText!)")
        return
    }

    if sheetNames.count.intValue == 0 {
        print("There are no sheets in the .xlsx")
        return
    }

    //  Get the name of the 1st sheet.
    var sheetName: String? = sheetNames.string(at: 0)

    //  Load the 1st sheet into the CSV.
    //  We could've also loaded the 1st sheet by passing an empty string for the sheet name.
    success = csv.xlsxLoadSheet(zip: zip, sheetName: sheetName)
    if success == false {
        print("\(zip.lastErrorText!)")
        return
    }

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

    var csvStr: String? = csv.saveToString()
    print("\(csvStr!)")

    //  Sample output:
    //  CompanyName,Address,City,State,Zip,Phone
    //  Acme Innovations LLC,7428 Westbrook Blvd,Oak Bend,IL,60514,630-555-2398

    //  NovaTech Solutions Group,578 Marketview Drive,Clearwater,FL,33760,727-555-6032

    //  Save to a .csv file.
    success = csv.saveFile2(path: "c:/temp/qa_output/fakeCompanies.csv", charset: "utf-8")
    if success == false {
        print("\(csv.lastErrorText!)")
        return
