What Tools Do Data Analysts Use?


SQL is widely used for data analysis in major corporations, and it is regarded as one of the most important tools for analysts. SQL is also used in software development by software engineers. SQL is a computer language that was designed to manage data from relational databases. It is a simple tool to learn and may be used for complicated, difficult data analyses. It is a popular option among data analysts since the code is simple to read and comprehend, and it can be used to edit and update data. Furthermore, it allows you to compile data in a way similar to Excel, but over enormous datasets and across numerous tables at once.

Microsoft Excel

Excel, a data analysis industry standard, is the most important tool to master as a data analyst. It is a simple application to learn, and data analysts should be adept in all parts of Excel, from formula to pivot tables. Any spreadsheet application will work, although Microsoft Excel is the most popular. 


Analysts frequently require a statistical analysis programme such as SPSS in addition to the instruments listed above. SPSS is an excellent choice for freshly certified analysts (more on SPSS below). VBA - Visual Basic for Applications - may be required by more experienced data analysts. It is a programming language built exclusively for Excel and is frequently used in financial analysis. It is also Word and PowerPoint compatible. Matlab is another excellent tool for creating algorithms, building models, and analysing data.

Jupyter Notebooks

Project Jupyter is a one-of-a-kind service dedicated to the development of open-source software, open standards, and interactive computing services. It is compatible with a wide range of programming languages. As an open-source online tool, Jupyter Notebook allows you to create and share documents that may contain live code, equations, graphics, and narrative prose. The notebook may be used for a variety of purposes, including data cleansing and transformation, machine learning, and more.


The open-source programming language R, which is compatible with all platforms (Windows, Mac OS, and Linux), is another important and widely used tool in data analytics. It is widely used by statisticians for statistical modelling because it provides a wide range of statistical and graphical options, and it is frequently used to undertake data wrangling. It allows the data analysts to create data visualisations such as plots and graphs and is accessible in a variety of libraries such as Plotly. It's employed in banking and sales, as well as several scientific sectors including medicine and technology. To use this data analysis tool, you must have a basic understanding of statistics and programming in general.


Tableau is another application that is often used by data scientists. It is widely utilised since data can be evaluated fast with it. Dashboards and spreadsheets are also created for visualisations. Tableau enables the creation of dashboards that deliver actionable information and propel a business ahead. When configured with the appropriate underlying operating system and hardware, Tableau products always run in virtualized environments.


SAS (Statistical Analysis System) is a well-known commercial suite of business intelligence and data analytics tools. The SAS Institute created it in the 1960s, and it has evolved since then. Its primary applications now are client profiling, reporting, data mining, and predictive modelling. Designed for the business market, the software is often more robust, adaptable, and user-friendly for large enterprises. This is due to the fact that they have differing amounts of in-house programming competence.

Microsoft Power BI

Microsoft Power BI is a relative newcomer to the market of data analytics tools, having been around for less than a decade. It originated as an Excel plug-in before being updated as a full suite of corporate data analysis tools in the early 2010s. Power BI helps users to quickly and easily generate interactive visual reports and dashboards. Its key selling point is its excellent data connectivity—it works well with Excel (as one would expect from a Microsoft product), but also with text files, SQL servers, and cloud sources such as Google and Facebook analytics.
