Rank Descending and Update Field

							
							//This script will grab the rows from the chosen table, rank them, and then update the chosen column

output.text("This code will let you pick a field you want your rows ranked by, and then rank it in descending order.");

//Allow the user to choose the table they want to manipulate
let table = await input.tableAsync('Select the table');

//You can replace the above line with the following if you know what table you're going to be using
//let table = base.getTable("[TABLE NAME]")
//For the purposes of this example base, it would be:
//let table = base.getTable("Sales");


//Allow the user to choose the field they want to rank
let fieldToRank = await input.fieldAsync("Select the field you want to rank by.  Please pick a number, percent, or currency field.", table);

//You can replace the above line with the following if you know which field you're going to be ranking by
//let fieldToRank = table.getField("[FIELD NAME]")
//For the purposes of this example base, it would be:
//let fieldToRank = table.getField("Amount")

//Check whether the fieldToRank is a number, percent, or currency field to ensure it works as intended.  If it's not, stop the code and inform the user why
if (fieldToRank.type === "number" || fieldToRank.type === "percent" || fieldToRank.type === "currency"){

	//Allow the user to choose the field they want to update with the rank number
	let fieldToUpdate = await input.fieldAsync("Select the field for the rank number", table);
	//You can replace the above line with the following if you know which field you're going to be updating with the rank number
	//let fieldToUpdate = table.getField("[FIELD NAME]")
	//For the purposes of this example base, it would be:
	//let fieldToUpdate = table.getField("Rank Number")

	//Shows the user some text so they know something's happening
	output.text("Running...");

	//Selects the records from the table and then sorts it by descending
	let query = await table.selectRecordsAsync({
	    sorts: [
	        {field: fieldToRank, direction: "desc"},
	    ]
	});

	//Create a variable that we will update to get the rank number
	let rankNumber = 0;
	//Since it has already been sorted, all we need to do is create the rank number as we loop through the result
	for (let record of query.records) {
		//Add 1 to the rank number
		rankNumber++
		//Update the selected field of the row with the rank number
		await table.updateRecordAsync(record.id, {
		    [fieldToUpdate.name]: rankNumber,
		})

		//Whenever the loop runs three times, show a "Still running" message to the user so that they know something is still happening
		if (rankNumber % 3 === 0 ){
			output.text("Still running...");
		}
		//Show a "Done" message to the user once the loop is complete
		if (rankNumber === query.records.length){
			output.text("Done!");
		}

	output.text("Sorry, the field you selected is not a number, percent, or currency field. Please start over.");

It’s really basic, but I wanted to put it out there in case someone found it useful.
