Google Sheets and JavaScript with Node.js



If you’d like to use the data in your Google Sheets projects from your Node applications, this is the guide for you.

We’ll use the google-spreadsheet module (https://www.npmjs.com/package/google-spreadsheet) by Theo Ephraim (https://twitter.com/theozero) to access an example spreadsheet inside of Google Sheets.

  8. Thank you for the amazing video. I understand this is a old video but when i'm working on it error pop outs and said googleSpreadsheet is not a constructor is there any way to solve this?

    anyone have solution

  14. Hi, thanks for this video. Although I think something has changed in Google-Spreadsheet. I'm using the exact same code like you but getting an error back each time.

    This is the code:
    const { GoogleSpreadsheet } = require('google-spreadsheet');

    const { promisify } = require('util');

    const creds = require('./blablabla.json');

    async function accessSpreadsheet() {

    const doc = new GoogleSpreadsheet('xxxxxxxxxxxxxxxxxxxxxxx')

    await promisify(doc.useServiceAccountAuth)(creds)

    const info = await promisify(doc.getInfo)();

    const sheet = info.worksheets[0];

    console.log(`Title: ${sheet.title}, Rows: ${sheet.rowCount}`)

    }

    accessSpreadsheet();

    The error I get back over and over again is:
    (node:5132) UnhandledPromiseRejectionWarning: TypeError: Cannot set property 'jwtClient' of undefined

    Anyone has a solution?

  18. Hii. Thankyou, your video is amazing S2.

    I have a issue when i try to use the code below:
    `————————–
    async function accessSpreadsheet() {

    await promisify (doc.useServiceAccountAuth)(creds);

    const info = await promisify(doc.getInfo)();

    const sheet = info.worksheets[0]; ///busca as informações

    const data = await promisify(sheet.getRows)({
    query: `data = ${datainput}`
    });

    return data.length;

    }

    var total = accessSpreadsheet();

    console.log(total);
    `——————————
    But it return: Promise { <pending> }

    I need to use the value "data.lenght" in another piece of code. What i need to do to use this variable?
