Ruby Requires Chilkat v11.3.0+

XLSX Convert Sheet to CSV

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

require 'chilkat'

success = false

#  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";

#  Sample output:

#  Save to a .csv file.
success = csv.SaveFile2("c:/temp/qa_output/fakeCompanies.csv","utf-8")

    print csv.lastErrorText() + "\n";
