Linearizing data can transform non-linear relationships into linear ones, simplifying analysis and forecasting in Excel. This process is crucial when dealing with complex data sets that require a straightforward linear trendline.

While Excel offers tools to linearize data, users often encounter challenges due to its steep learning curve and the complexity of its functions. In this guide, we'll cover the steps to linearize data in Excel and discuss why Sourcetable may provide a more user-friendly alternative for this task.

Linearizing Data in Excel

Curve Fitting in Excel

Excel provides tools to fit a curve to a dataset, enabling the extraction of meaningful trends and relationships. Utilize Excel's capabilities to graph a curve and derive polynomial coefficients, simplifying complex relationships into linear forms.

Linearization Process

To linearize data, Excel can drive an output from an input by applying transformation techniques. The process involves adjusting non-linear data points to a straight line, enhancing the predictability and interpretation of the results.

Graphing and Output

Graphing functions in Excel allow visualization of the linearization process. Displaying Vout against VR100, for instance, can clarify the relationship between variables, particularly in sensor output like RTD to a linear voltage range of 0-4V.

Excel for Polynomial Coefficients

Excel's capacity to calculate polynomial coefficients is essential in linearizing curves. These coefficients are fundamental in developing equations that represent linearized data, facilitating further analysis or application in various fields, such as driving a 20mA current loop with a linearized 0-4V output.

Excel vs. Sourcetable: Streamlining Data Management

Excel, the long-standing champion of spreadsheets, meets its innovative counterpart, Sourcetable. While Excel excels in data organization, Sourcetable revolutionizes data integration from various sources.

Unlike Excel, Sourcetable's AI copilot simplifies complex tasks, offering real-time assistance in formula creation and template design through an intuitive chat interface, making data analysis more accessible.

Sourcetable's unique selling point lies in its ability to consolidate disparate data streams into a single, query-friendly interface, a feature not native to Excel, which enhances efficiency for multi-source data management.

For businesses and analysts seeking a unified data solution, Sourcetable's AI-driven, integration-focused platform contrasts with Excel's traditional, manual approach to spreadsheet management.
