Google Sheets export

1. Create a sheet

1. Open sheets.new
2. Row 1: column headers matching your Pluck job (e.g. title, price)

2. Apps Script

In the sheet: Extensions → Apps Script. Replace Code.gs with:

function doPost(e) {
  var payload = JSON.parse(e.postData.contents);
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();

  var lastCol = sheet.getLastColumn();
  var headers = lastCol > 0
    ? sheet.getRange(1, 1, 1, lastCol).getValues()[0]
    : [];

  if (headers.length === 0 && payload.columns && payload.columns.length > 0) {
    sheet.getRange(1, 1, 1, payload.columns.length).setValues([payload.columns]);
    headers = payload.columns;
  }

  var rowsToAppend = payload.rows.map(function (row) {
    return headers.map(function (h) { return row[h] != null ? row[h] : ''; });
  });

  if (rowsToAppend.length > 0) {
    sheet
      .getRange(sheet.getLastRow() + 1, 1, rowsToAppend.length, headers.length)
      .setValues(rowsToAppend);
  }

  return ContentService
    .createTextOutput(JSON.stringify({ ok: true, appended: rowsToAppend.length }))
    .setMimeType(ContentService.MimeType.JSON);
}

3. Deploy as web app

1. Deploy → New deployment → Web app
2. Execute as: Me
3. Who has access: Anyone (required for Pluck to POST)
4. Copy the web app URL (ends in /exec)

4. Paste into Pluck

Extension popup → edit job → enable Append rows to a Google Sheet → paste the URL → Save.
