Start to learn Swift and iOS development

Posted on October 9, 2019 by j5423

My plan is to spend one hour every weekday for a year and let’s see what I learn. Today is day one and I learned something about how to use a function in NSString -enumerateLines. I know it accepts a block (a closure) and the closure has two parameters (line and stop). Here is an example as how to use it:

import Foundation


let str = "Hello, \r\nplayground\r\nSomething else"

str.enumerateLines { (line, _) in print(line) }

Excel file to big to be converted to Google sheet on Google Drive

Posted on June 12, 2019 by j5423

Here is the solution:
“Just to confirm, are you trying to convert Microsoft Excel file to Google Docs or Google Sheets?

If you are converting it to a Google Sheets file, the maximum cells that can be used on Google Sheets is up to 2 million cells which includes the amount of blank cells on your spreadsheet. To optimize your spreadsheet, I would suggest to delete blank rows and columns. You can try using COUNTA() and COUNTBLANK(). This should add up all of the cells that are empty and non-empty if added together.

If possible, break the spreadsheet down into smaller sheets by having a master spreadsheet and referenced spreadsheets. You can use IMPORTRANGE() function to import cells from one spreadsheet to another.”
