Detecting Cells with Quote Prefix in Google Spreadsheet using Google Apps Script
This is a sample script for detecting cells with the quote prefix in Google Spreadsheet using Google Apps Script.
For example, when a value is put to a cell by adding a single quote ' as the top character, the cell value is used as the string value. This is the current specification. Under this condition, when the cells with the value of the quote prefix are tried to be detected, unfortunately, in the current stage, it seems that there is no method for directly achieving this in the methods of Spreadsheet service (SpreadsheetApp).
