How can i get range number from A1notation? - google-apps-script

Question

This is a script to get a1notation from a number.
Conversely, I don't know how to get the number from a1notation !
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheets()[0];
var range = sheet.getRange(1, 1, 2, 5);
// Logs "A1:E2"
Logger.log(range.getA1Notation());
i want to get (1, 1, 2, 5) from "A1:E2"

Answer 1

Here is an example of how to get the row and column from A1 notation.
function test() {
try {
let spread = SpreadsheetApp.getActiveSpreadsheet();
let sheet = spread.getSheetByName("Sheet1");
let range = "A1:E2";
range = getRange(range);
console.log(range);
console.log( sheet.getRange(range[0][0],range[0][1],(range[1][0]-range[0][0]+1),(range[1][1]-range[0][1]+1)).getValues() );
range = "F3";
range = getRange(range);
console.log(range);
console.log( sheet.getRange(range[0][0],range[0][1]).getValue() );
}
catch(err) {
throw "Error in test: "+err;
}
}
function getRange(range) {
try {
let ranges = range.split(":");
ranges = ranges.map( text => {
let cell = text.toUpperCase();
let column = 0;
let row = 0;
let char = null;
for( let i=0; i<cell.length; i++ ) {
char = cell.charCodeAt(i);
if( ( char > 64 ) && ( char < 91 ) ) {
if( row > 0 ) return null;
column = (26*column)+char-64;
}
else if( ( char > 47 ) && ( char < 58 ) ) {
if( column === 0 ) return null;
row = (10*row)+char-48;
}
}
if( ( column === 0 ) || ( row === 0 ) ) throw "Incorrect range";
return [row,column];
}
);
return ranges;
}
catch(err) {
throw "\nError in getRange: "+err;
}
};
