Intrinsic to any script-based application is the notion of parsing. In CloudSheet, described in detail in the forthcoming TED Case Study entitled “Massively Scalable Graph-Based Computation in Azure,” a formula parser tokenizes arbitrarily complex Excel-like formulas making subsequent evaluation faste...
In first line we initialize the Spreadsheet_Excel_Reader, then we set the output encoding. Finally we read the Excel file using read method of Spreadsheet_Excel_Reader class. This basically completes the process of reading the excel spreadsheet. Simple isn’t it?
For example, my specific use case is to transform an Excel spreadsheet using only specific rows and columns into a CSV file with a subset of columns from the original file. If you’re like me and would like to stay in the Swift ecosystem, there are no great options. There’s anObjectiv...
