1) When you have Excel installed you can use the Office-Api in Visual-Studio and iterate through the lines. This means that all code is only working on systems that have a certain version of Excel. Using the native .xls-file-format with an own C-program is beyond the scope of this task. ->(best start, when you have used Active-X and COM/OLE, most native solution)

2) You save your file in the new XLSX (xml-based) and create a program that is based on an xml-parser going through all entries. ->(most cool "standard" solution that takes most time)

3) You save your file in .csv already (Excel can do that); then go through the lines with a program. ->(Most practicable solution for a pure "C"-person)

4) You buy a third-party tool like "Altova Mapforce Enterprise Edition" and click your program together, then let the tool generate your xls2csv tool. ->(Fastest solution, most expensive when you do not already own such a tool)
