Thanks so much posting this!!

Updated the script above to populate the headers in the sheet.

function coinPrice() {
const myGoogleSheetName = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Coins");
const coinMarketCapAPICall = {
method: 'GET',
uri: 'https://pro-api.coinmarketcap.com/v1/cryptocurrency/listings/latest?aux=cmc_rank',
qs: {
start: '1',
limit: '5000',
convert: 'USD',
},
headers: { 'X-CMC_PRO_API_KEY': 'YOUR_API_KEY_GOES_HERE' },
json: true,
gzip: true,
};

// Set column headers
const headers = [
"Symbol", "ID", "Name", "Slug", "Date Added", "Is Active", "Is Fiat",
"Num Market Pairs", "Circulating Supply", "Total Supply", "Max Supply",
"CMC Rank", "Price", "Volume (24h)", "Percent Change (1h)",
"Percent Change (24h)", "Percent Change (7d)", "Percent Change (30d)",
"Percent Change (60d)", "Percent Change (90d)", "Market Cap", "Last Updated"
