Alright, I could do it with a single task (Seriously :D).

Basically I'm using two sheets, one for the words to find and their replacements. The other one is where you add inputs and get the desired output.

I offloaded the computation to Google Sheets by using a custom script I wrote that you can find below.

This works by adding a new row to the second sheet, the input is the original string and the output is a formula that executes the script.

@ikbelkirasan - this is perfect! Thanks so much for this.

Could you possibly paste the code in text form here?

Thanks!

You're welcome! Here's the code.

function arrayToMap(array) {

return array.reduce(function(target, current) {

const key = current[0]

const value = current[1]

target[key] = value

return target

}, {})

}

function myFunction(input) {

var rows = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Sheet1').getDataRange().getValues();

rows = rows.filter(function(row, index){

return index > 0

});

const map = arrayToMap(rows)

const words = String(input).split(' ')

const results = words.map(function(word) {

const replacement = map[word]

if (replacement) {

return replacement

}

return word

})

const output = results.join(' ')

return output

}

And this is the formula:

=myFunction(INDIRECT(ADDRESS(ROW(),COLUMN()-1)))

Thanks again @ikbelkirasan - this is a great help!
