Seven files, plus this readme file, are contained in the zip data ExcelToKmlDemo.xls, which has five worksheets. The web page www.earthpoint.us/ExcelToKml.aspx processes all of the worksheets together. To demonstrate that extra data is allowed without any problem, the spreadsheet also contains additional columns of data and a chart. These are ignored by ExcelToKml. ExcelToKml also converts txt (tab-delimited) files and csv (comma-separated-values) files. As part of the sample data, the three worksheets have been saved as txt and csv files as follows. ExcellToKmlDemo1.txt ExcellToKmlDemo2.txt ExcellToKmlDemo3.txt ExcellToKmlDemo4.txt ExcellToKmlDemo5.txt ExcellToKmlDemo1.csv ExcellToKmlDemo2.csv ExcellToKmlDemo3.csv ExcellToKmlDemo4.csv ExcellToKmlDemo5.csv
