What is a Query in Google Sheets?

A query in Google Sheets is a powerful tool that allows you to extract specific data from a large dataset. It’s like asking a question to your data, and Google Sheets responds with the answer. Queries can be used to filter, sort, and manipulate data, making it easier to analyze and visualize your data.

Why Write a Query in Google Sheets?

There are many reasons why you should write a query in Google Sheets. Here are a few:

  • Extract specific data: Queries allow you to extract specific data from a large dataset, making it easier to analyze and visualize your data.
  • Filter data: Queries enable you to filter data based on specific conditions, such as dates, numbers, or text.
  • Sort and manipulate data: Queries allow you to sort and manipulate data in various ways, such as grouping, aggregating, and pivoting.
  • Save time: Writing a query can save you a significant amount of time compared to manually filtering and manipulating data.
  • Improve accuracy: Queries can help you avoid errors and inaccuracies that can occur when manually manipulating data.

Basic Query Syntax

The basic syntax of a query in Google Sheets consists of the following elements:

  • Select: specifies the columns you want to retrieve.
  • From: specifies the range or table you want to query.
  • Where: specifies the conditions for which you want to retrieve data.
  • Group by: specifies the columns you want to group the data by.
  • Order by: specifies the columns you want to sort the data by.

Here’s an example of a basic query:

SELECT A, B, C
FROM Sheet1
WHERE A > 10
