问题 I want to import from excel sheet format (.xls) to mysql database through phpmyadmin importing option. I understand that we need to convert the format to csv format first before we can import to the phpmyadmin. But unfortunately if I change to csv some special character or symbol will become question mark (?) or other different character/symbol. Please advise me on this as I am really new to phpmyadmin. Thanks 回答1: I have answered similary question here https://stackoverflow.com/a/16330428

问题 Background : I'm running Go on GAE and using Mux for my router. In order to fetch a URL GAE requires that I use its built in urlFetch capability. I want to make this URL fetch happen during my modules init() but as far as I can tell I can only use urlFetch when invoked via a handler. func init() { r := mux.NewRouter() r.HandleFunc("/", homeHandler) r.HandleFunc("/about", anotherHandler) http.Handle("/", r) } GAE suggests the following code for making a urlFetch: c := appengine.NewContext(r)

问题 I need to generate Excel documents with Ruby (from Rails) on a Linux machine. I know of Spreadsheet::Excel, but it doesn't support formulas, and uses a pretty old format. Is there any other option, not necessarily free or open source, that is a bit more powerful? 回答1: How about opening a spreadsheet (Spreadsheet::Excel) with the formulae already populated. Entering data into the referenced cells will cause them to display the result. 回答2: How about https://github.com/randym/axlsx This gem can

问题 I am trying to iterate a COUNTIF formula that counts the number of cells in each row containing numbers greater than 4. I am trying to use ArrayFormula to do this but it isn't working. Unfortunately it counts ALL the cells matching the condition across the entire range B2:G39 resulting in 26 being entered in each row of column K rather than row by row count i.e. number of cells >4 in B2:G2 entered in K2, number of cells >4 in B3:G3 entered in K3 This is the formula =ARRAY_CONSTRAIN

问题 With Spreadsheet::WriteExcel, I can create a new workbook, but what if I want to open an existing book and modify certain columns? How would I accomplish that? I could parse all of the data out of the sheet using Spreadsheet::ParseExcel then write it back with new values in certain rows/columns using Spreadsheet::WriteExcel, however. Is there a module that already combines the two? Mainly I just want to open a .xls , overwrite certain rows/columns, and save it. 回答1: Spreadsheet::ParseExcel
