Our customers used to use Excel or other tools that aren’t adapted to data discovery like Tableau is. Now we can drag dimensions and measures, see if this or that visualization works, and optimize to get the insights we need. We easily iterate and don’t have to rely on a long development process. We can share with other employees, and this gives our customers a ‘wow’ experience because they’re used to having reports built by an IT department—and now they can do it all themselves.

Tableau is used by tens of thousands of businesses to analyze and generate insights from their data. Most businesses also use Excel, which has been the most popular spreadsheet application. While Excel allows users to evaluate data and do calculations, Tableau uses visual analytics to give users a new method to interact with and analyze data. Tableau users can engage with data graphically to uncover insights faster and make vital decisions that enhance customer service and improve business. However, the biggest advantage of integrating Tableau Excel is that Tableau links directly to Excel files, making data analysis quick and easy.
This post will walk through the steps to set up the Tableau Excel Integration. You will understand the importance of integrating Tableau Excel and also discover some of the significant tips to format your Excel data before loading it to your Tableau. Before you get started, let’s get familiar with Tableau and Excel and why are they so popular in the market.

What is Excel?
Microsoft Excel is a Microsoft Spreadsheet Application that is part of the Microsoft Office Suite of Applications. It is compatible with Windows, macOS, & Android. It facilitates the generation of text and numeric grids, and supports calculation formulae, graphing tools, pivot tables, and the VBA(Visual Basic for Applications) macro programming language.
Microsoft Excel is used to record data in the form of tables. The information might be anything from a regular planner to an organization’s spending data. It also assists in the analysis and display of data recorded in spreadsheets.
Key Features of Excel
Some of the key features of Microsoft Excel are:
- Built-in Formulae: Excel supports basic to complex built-in formulae for sum, average, minimum, and others.
- Conditional Formatting: You can apply formatting to a cell or a range of cells in MS Excel, and the formatting will change depending on the cell’s value or the value of a formula.
- Data Sorting & Filtering: In Excel, you can quickly execute simple data sorting and filtering operations on your data. It also supports advanced filtering options.
- Index-Match: Index-Match is one of the most powerful Excel function combinations. It can seek a value in a Big Data Table and return its equivalent.
- Protection & Security: Microsoft Excel safeguards your work in a variety of ways, such as preventing unauthorized access to a Workbook, allowing Read-Only access, or simply protecting a Worksheet so that no equations are accidentally removed. MS Excel also has a reliable data recovery solution.

Tableau Tips for Working with Your Excel Data
Data can be arranged in many ways. Tableau advises users to connect to Excel data that has been structured for analysis to get the most out of Tableau Desktop. Some of the points to keep in mind while loading your Excel data to your Tableau are:
1) Tableau Excel Tip: Remove Pre-Aggregated Data
Data is frequently pre-aggregated. That is, data can include sums, averages, and medians, among other things. Subtotals and grand totals are two examples of pre-aggregated data that are commonly used. The data for subtotals and grand totals are computed from the raw data, but it is not part of the original data. Pre-aggregated data must be eliminated in this scenario.
Remove pre-aggregated data from your table manually and then using the totals option, you can link to your Excel data from Desktop and produce subtotals and totals. Or you can connect to your Excel data from Desktop, activate Data Interpreter, and then select the totals option.
2) Tableau Excel Tip: Pivot Data in Crosstab Format
Tableau Desktop is designed to work with data that is organized in rows. Variables are kept as row values in a row-oriented table. The table is column orientated when the data is presented in crosstab format. Variables are kept as column headers in a column-oriented table. By manually altering your Excel data, you can pivot the columns in the rows. Or you can connect to your Excel data from a desktop computer and then use the pivot option.
3) Tableau Excel Tip: Remove/Exclude Introductory Text
Titles or blocks of introductory text can be included in Excel data that is presented as a report. This information might cause complications during your analysis since Tableau Desktop requires either column headers or row values in the first row of a table. To remove the introductory text, you can follow one of the following methods:
- Remove this data from your Excel spreadsheet manually. Then, from the Desktop, connect to your Excel data and use the title option to add a report title.
- Connect to your Excel data using Desktop, then switch on Data Interpreter and select the title option.
4) Tableau Excel Tip: Flatten Hierarchical Headers
Tableau Desktop requires column headings in the first row of your Excel data. Multiple layers of column headers in your data might pose issues during analysis. The hierarchy of headers must be flattened or deleted in this scenario. You can accomplish this by manually creating a new column in your Excel data for each hierarchy heading or using Tableau Desktop to connect to your Excel data and then switching on Data Interpreter.
5) Tableau Excel Tip: Remove Blank Rows
You should make sure that your data doesn’t have any blank rows. To delete blank rows, you must first remove them from your Excel data.
