In Excel, queries are great for managing data! Why? They let you quickly find exactly what you need from all sorts of sources simply by setting some simple rules.
In Excel, a query is a way to retrieve and process data from internal or external sources. It allows you to use structured query language (SQL) or a graphical interface to filter, sort, and manipulate data from databases, text files, other spreadsheets, or web services directly within Excel.
Also, With queries, you can define specific criteria to selectively extract and display the data you need for analysis or reporting.
In this article, we’ll show you Excel queries, the different kinds you can use, and how to set them up quickly.
We’ll also look at how queries make sorting through data and creating reports much easier!
Are you ready to master Excel and simplify your data tasks like never before?
Let’s get started!
What Are The Types of Queries in Excel?
When working with queries in Excel, you can choose between two types: internal and external queries.
Internal queries allow you to sift through data in an Excel workbook, pulling information from multiple tables without needing external sources. This is perfect for consolidating data across different sheets without relying on additional tools or programs.
On the other hand, external queries connect to external data sources, allowing you to tap into a broader range of data. Examples of these external sources include SQL Server databases, text files, Access databases, and even Power BI.
As for static vs dynamic queries, here’s what you need to know:
One fantastic feature of queries in Excel is how they handle changes to the original data. Static queries serve as a snapshot, preserving the data as it was retrieved, which requires a manual refresh to access updated content.
Whereas dynamic queries are agile, automatically reflecting changes in the underlying data, thus saving precious time and reducing manual work when handling evolving datasets.
Now, let’s take a look at how to construct a query.
How to Create a Query in Excel
To create a query in Excel, follow these three simple steps:
Specify the data range or table name: Begin by identifying the specific data you wish to retrieve. You can either select a cell range containing the desired information or refer to an existing table within your workbook.
Define the criteria for selecting data: Once you’ve identified the relevant data, set the criteria that will determine which records should be included in your query results. For example, you might choose to filter based on equality, inequality, containment, or other conditions appropriate for your dataset.
Choose how you want the query results to be displayed: Finally, decide how you would like the query results to appear in your workbook. Options include creating a new worksheet, inserting a table to organize the output, or even embedding the query directly into an existing worksheet or chart.
Next, let’s explore creating a query with some real-world examples.
Example 1: students and their grades in an exam
Suppose you have a list of students and their grades in an exam. You want to find out the average grade for all students who scored above 70.
Here’s a step-by-step on how to formulate a filter query:
Example 1: Basic Filtering
Select the Range and Apply the filter
How to Apply the Filter:
Select the range of cells containing the grades (let’s say these are in cells C2:C10).
Click on the Data tab in the ribbon menu.
Under the ‘Sort & Filter‘ group, click on the ‘Filter‘ button (it looks like a funnel icon). This will add drop-down arrows to each column header.
Set the Filter Options
Go to column B and click on the drop-down, expand the number filters options and select “Greater Than”, then enter “>70“. This sets up a filter so that only values greater than 70 are displayed.
Now let’s combine the query with a basic formula.
Combine With A Formula
Now go to cell B1 and type the formula “=AVERAGE(C2:C10)“. Since we’re only looking at values greater than 70, this formula will calculate the average of those values.
That’s it! By setting up filters and using a simple formula, you’ve formulated a query to get the information you need.
Now, let’s take a deeper look at using queries with Formulas and Functions.
How to Use Queries in Formulas and Functions
One of the most powerful aspects of Excel queries lies in their ability to be seamlessly integrated into various formulas and functions.
Let’s take a look at some examples of combining queries with functions:
Example 1: High Earners Query
Select the Range
Imagine you want to pinpoint which members of your team are in the top earning bracket. Begin by selecting the range that includes employee names and corresponding salaries, which we’ll refer to as the “Salary_Range” in your spreadsheet.
Now, we’re going to set our criteria and apply the filter.
Apply The Filter
Let’s apply a filter criterion for salaries set as “Salary > 60000“. Execute the query, and then direct the output to a fresh worksheet named “Top_Earners”.
This action generates a streamlined list of individuals who are earning above $60,000.
Next up, we’ll dissect an example query focused on analyzing regional sales.
Example 2: Regional Sales Analysis Query
Apply the Filter
Let’s say you aim to dissect your product performance in the Northwest region. Start with your comprehensive sales dataset, which we’ll call “Product_Sales_Data”.
Define your filter criterion to hone in on the Northwest area, go to the drop-down and select “text filter” and “equals..” using a parameter like “Region contains ‘Northwest'”.
View the Filtered Results
Now you should only see the products that meet those criteria in the list after applying the filter.
Example 3: Total Sales for a Specific Product
If you want to calculate the total sales for ‘Widget A’ in the ‘Electronics’ category. First, we filter the dataset using a query to show only ‘Electronics’ products.
Then we apply the SUMIFS function:
=SUMIFS([Total Sales], [Product], "Widget A", [Category], "Electronics")
This formula gives us the total sales for ‘Widget A’ after filtering out only the electronics.
By harnessing the power of queries within your formulas and functions, you can optimize your data analysis process and uncover valuable patterns and trends hidden within your dataset.
Alright, now that we’ve covered creating some queries, let’s check out how to edit and manage them.
How to Edit and Manage Queries
Once you have created a query, it’s important to manage and edit as needed to ensure accurate and up-to-date results. This involves modifying the query criteria, updating the data range, or adjusting how the results are displayed.
For example, if your initial filter was too broad and now you need to refine it further, simply change the criteria or add additional conditions to narrow down the selection.
Additionally, if the source data has been updated, remember to refresh the query to incorporate these changes.
To maintain a well-organized workbook, consider deleting or renaming queries that are no longer relevant or reorganizing them into logical groups for easier access.
By regularly editing and managing your queries, you can streamline your processing and minimize potential errors caused by outdated or incorrect information.
Now that we’ve covered the basics, let’s see how queries supercharge your formulas and functions.
How to Create and Enhance Data Queries with Excel Power Query
When you jump into Excel’s Power Query feature, you’ll be blown away by its incredible ability to bring in data from all sorts of places.

Bringing in and Shaping Data
Power Query is great for pulling in data, whether it’s from an Excel table, a CSV file, or another source.
To import Data from a table, select “Get Data”, on the drop-down, select “From other sources” then select “From Tables/Ranges”. Now all your data from the table should be displayed in the power query editor.
It’s also handy when you need to combine or tweak your data, like merging lists or sorting information from different tables.
Next, let’s dive deeper into Power Query’s many features.
Getting to Know the Power Query Editor
In the Power Query Editor, you can change your data in many ways—like rearranging columns or only showing certain rows.
This tool has lots of options to help you transform your data just how you need it, with a special section for making these changes and a sidebar to help you keep track of them.
Grouping and Summarizing Data
Another useful function of queries is their ability to group and summarize data. In the Query Editor, you can group your data by specific categories (such as student names or course subjects) and then calculate summary statistics like counts, averages, or totals for each group.
This helps you quickly identify patterns and make informed decisions based on your analysis.
If you have multiple tables or datasets that you need to combine, queries make it easy to merge them into one cohesive dataset. In the Query Editor, simply add another table or query to your current one and use the “Merge” option to combine them.
You can then further refine and transform the combined data as needed.
In Power Query, the merging options are:
Inner Join: Combines rows that have matching values in both tables.
Left Join: Includes all rows from the left table and matched rows from the right table. Rows from the left table without matches in the right table have blanks for the right table columns.
Right Join: Includes all rows from the right table and matched rows from the left table. Rows from the right table without matches in the left table have blanks for the left table columns.
Full Outer Join: Includes all rows from both tables. Rows without matches in the other table have blanks for the missing side’s columns.
Anti Join: Includes rows from one table that do not have matching rows in the other table.
Now that we’ve covered some basics of creating and using queries in Excel, let’s explore connecting to various data sources with Excel’s versatile tools.
Data Source Connection
The beauty of queries lies in their ability to pull data from various sources.
Here are some common types of data sources:
Internal Excel Workbook: You can create a query based on data within the same workbook, such as another worksheet or table. This is useful when you have related datasets that need to be combined or analyzed together.
External Databases: Queries can connect to external databases like Microsoft Access, SQL Server, or Oracle. This allows you to access large amounts of structured data stored in databases without having to import the entire dataset into Excel.
Web Pages: Using queries, you can extract data from HTML tables found on public or intranet websites. This is particularly helpful for monitoring market trends, tracking competitors, or gathering industry-specific information.
Text Files: Queries can also retrieve data from plain text files (e.g., .txt, .csv) stored locally or online. This is ideal for working with simple lists or tabular data that doesn’t require a full-fledged database management system.
Other Spreadsheets: If you have multiple Excel workbooks containing related data, you can create a query that pulls information from one or more of these files.
Queries are super helpful because they let you connect to so many different types of data sources, making it a breeze to analyze and understand even the most complicated information.
Next, let’s examine how to keep your data up-to-date by refreshing queries.
How to Refresh Queries
In Excel, refreshing a query means updating the data it pulls from its source. This is particularly useful if your dataset changes regularly, such as daily sales figures or weekly employee performance reports.
To refresh a query in Excel, follow these steps:
Click anywhere in the query results (the filtered list of students and their grades in our previous example).
On the Data tab in the ribbon menu, click the arrow next to ‘Refresh All’ and then select ‘Refresh’. Alternatively, you could right-click any cell within the query results and choose ‘Refresh’ from the context menu.
As for query management, Excel provides tools to help manage these data connections and queries. You can edit, delete, or view properties of a query by right-clicking any cell within the query results and selecting the appropriate option from the context menu.
Moving forward, let’s see how to optimize our queries for the best performance.
How to Optimize Query Performance
Optimizing query performance is indeed crucial, especially when dealing with large datasets.
To optimize query performance:
Filter Data at the Source: Pre-filtering data in the database can lead to quicker query times by reducing the volume of data Excel processes.
Limit Columns and Rows: Import only what’s necessary to streamline your query’s execution—less data means faster results.
Use Indexes and Keys: Implement indexes and keys in your database to expedite the search and retrieval process for your queries.
Understand Query Folding: Utilize query folding to perform operations directly in the database, minimizing the data load to Excel and enhancing efficiency.
Utilize Advanced Features: Take advantage of Excel’s advanced features, like PivotTables and Power Query, to manage and analyze your data with greater agility and less overhead.
