Google Apps Script is a cloud-based scripting language for light-weight application development in the G Suite platform. To start, open your Google Sheet and navigate to Extensions > Apps Script. This opens the Apps Script editor where you can write and run your script.

In the Apps Script editor, write a function to read data from your Google Sheet. Use the `SpreadsheetApp` service to access your sheet and extract the data. For example:
```javascript
function getDataFromSheet() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
var data = sheet.getDataRange().getValues();
return data;
}
```
This function retrieves all the data from the active sheet.

Once you have the data, you may need to format it before sending it to Redis. This could involve converting arrays to JSON strings or any other format that suits your Redis structure. You can modify the `getDataFromSheet` function to include this formatting.

Ensure you have access to a Redis server. You can set this up locally or use a cloud-based Redis service. For local setup, download and install Redis from the official website. Start the Redis server by running `redis-server` in your terminal.

To interact with Redis, you need a Redis client library for Node.js. This requires setting up a Node.js environment. Install Node.js on your machine and use npm (Node Package Manager) to install the Redis client by running:
```bash
npm install redis
```

Create a Node.js script that connects to your Redis server and imports the data from Google Sheets. Use the following sample code as a guide:
```javascript
const redis = require('redis');
const client = redis.createClient();

client.on('connect', function() {
console.log('Connected to Redis');
});

async function pushDataToRedis(data) {
data.forEach((row, index) => {
client.set(`row:${index}`, JSON.stringify(row), redis.print);
});
}

// Call your function to get data from Google Sheets here
const data = getDataFromSheet(); // Assume this is the data you got from Google Apps Script
pushDataToRedis(data);
```

Execute your Google Apps Script to extract the data and format it. Then run your Node.js script to push this data to Redis. Verify the data in Redis using the Redis CLI by running commands like `KEYS *` and `GET row:0` to ensure the data was transferred correctly.

By following these steps, you can directly move data from Google Sheets to Redis without relying on third-party connectors or integrations. This method gives you full control over the data transfer process.
