Google app script to conditional format cell border - google-sheets

Question

Sorry to ask dumb question.
But I really need help
I have a google sheet with 26 columns and 96 raws. I want to change the cell border thickness if cell contain text which is same to Z6 cell value. Is there a way to write a google app script code for this.
I tried this code but failed
function formatting() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Chart');
var range = sheet.getRange("A1:Z100")
var ruleRed = SpreadsheetApp.newConditionalFormatRule()
.whenFormulaSatisfied("=$Z$6")
.setBackground("green")
.build();
}
PlEASE HELP

Answer 1

Several things:
The correct formula for conditional formatting would be:
"=A1=$Z$6"
The correspoding request in Apps Script including the necessary setting of ranges would be:
var ruleRed = SpreadsheetApp.newConditionalFormatRule() .whenFormulaSatisfied("=A1=$Z$6") .setBackground("green") .setRanges([range]) .build();
After creating a conditional rule, you need to apply to the sheet, e.g. sheet.setConditionalFormatRules([ruleRed]);
However
Borders cannot be formatted in scope of conditional formatting, you need to take another approach
You can use the Apps Script method setBorder()
To set borders as required in Apps Script, you need to
retrieve the value of Z6
Loop through your range comparing all values to Z6
Assign the border to each cell fulfilling the condition
Sample for border formatting and conditional formatting with Apps Script:
function formatting() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Chart');
var range = sheet.getRange("A1:Z100")
//border formatting
var value = sheet.getRange("Z6").getValue();
var values = range.getValues();
for (var i = 0; i < values.length; i++){
for (var j = 0; j < values.length; j++){
if (values[i][j] == value){
range.getCell(i+1, j+1).setBorder(true, true, true, true, false, false);
}
}
}
//conditional formatting
var ruleRed = SpreadsheetApp.newConditionalFormatRule()
.whenFormulaSatisfied("=A1=$Z$6")
.setBackground("green")
.setRanges([range])
.build();
sheet.setConditionalFormatRules([ruleRed]);
}
