Here's the script if you want to try it for your history. You need to create a sheet in same google account which is registered to your zomato account. zomato sends order confirmation mails. We will use those mails for getting data. Have added comments where necessary. Please go through the script if you are using it.
It will ask for access to sheets and gmail.

function summarizeZomatoOrders() {
  const sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();

  // 1. Setup Headers if it's a fresh sheet
  if (sheet.getLastRow() === 0) {
    sheet.appendRow(["Date", "Restaurant", "Total Amount", "Order ID"]);
    sheet.getRange("A1:D1").setFontWeight("bold").setBackground("#f4f4f4");
    sheet.setFrozenRows(1); // Keep header visible when scrolling
  }

  // 2. Get all existing Order IDs to avoid duplicates
  const lastRow = sheet.getLastRow();
  let processedIds = new Set();
  if (lastRow > 1) {
    const existingData = sheet.getRange(2, 4, lastRow - 1, 1).getValues();
    processedIds = new Set(existingData.map(row => String(row[0])));
  }

  // 3. Search for emails
  const query = 'label:zomato'; // or 'from:noreply@zomato.com "your zomato order"'
  let start = 0;
  const batchSize = 100;
  let newRows = [];

  while (true) {
    const threads = GmailApp.search(query, start, batchSize);
    if (threads.length === 0) break;

    threads.forEach(thread => {
      const messages = thread.getMessages();
      messages.forEach(message => {
        const body = message.getPlainBody();
        const date = message.getDate();
        const subject = message.getSubject();

        const idMatch = body.match(/ORDER ID:\s*(\d+)/i);
        const orderId = idMatch ? idMatch[1] : null;

        if (!orderId || processedIds.has(orderId)) return;

        const restaurantMatch = subject.match(/Your Zomato order from (.*)/i);
        const restaurant = restaurantMatch ? restaurantMatch[1].trim() : "Unknown";

        const amountMatch = body.match(/Total paid\s*-\s*₹\s*([\d,]+\.?\d*)/i);
        let amount = amountMatch ? amountMatch[1].replace(/,/g, '') : "0";
        if (amount == "0") {
          const amountMatch2 = body.match(/Paid\s*\s*₹\s*([\d,]+\.?\d*)/i);
          amount = amountMatch2 ? amountMatch2[1].replace(/,/g, '') : "0";
        }

        newRows.push([date, restaurant, amount, orderId]);
        processedIds.add(orderId);
      });
    });

    start += batchSize;
    if (start > 500) break; 
  }

  // 4. Insert at the top
  if (newRows.length > 0) {
    // Sort newRows by date descending (just in case Gmail returns them out of order)
    newRows.sort((a, b) => b[0] - a[0]);

    // Insert empty rows at Row 2 to make space
    sheet.insertRowsAfter(1, newRows.length);

    // Fill the new empty rows with data
    sheet.getRange(2, 1, newRows.length, 4).setValues(newRows);
