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

# .xlsx files are Zip archives
zip = Chilkat::CkZip.new()
success = zip.OpenZip("qa_data/excel/fakeCompanies.xlsx")
if (success == false)
    print zip.lastErrorText() + "\n";
    exit
end

csv = Chilkat::CkCsv.new()
sheetNames = Chilkat::CkStringTable.new()
success = csv.XlsxGetSheets(zip,sheetNames)
if (success == false)
    print csv.lastErrorText() + "\n";
    exit
end

if (sheetNames.get_Count() == 0)
    print "There are no sheets in the .xlsx" + "\n";
    exit
end

# Get the name of the 1st sheet.
sheetName = sheetNames.stringAt(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,sheetName)
if (success == false)
    print zip.lastErrorText() + "\n";
    exit
end

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

csvStr = csv.saveToString()
print csvStr + "\n";
