Where do Tableau formulas, SQL and scalar DAX run?
Tableau formulas run through xmetric’s calculation and view services. SQL queries run in DuckDB compiled to WebAssembly. DAX measures use xmetric’s Power BI evaluator over one table named Sales. Level-of-detail expressions and aggregates become SQL where supported; table calculations run over ordered result rows with the chosen addressing and partitioning. Each editor runs independently.
How can I run Tableau, SQL and scalar DAX on my CSV?
Use the formula playground to evaluate editable JSON rows or your CSV in this browser. Each language runs independently on the rows you supply.

What formula and inputs define this worked example?
This worked example uses 8 explicitly supplied input rows and their stated field types. Published inputs, field types and recorded results (JSON) identify the exact example.
The formula for this published example is:
IFNULL([amount], 0)Tableau calculation documentation provides the language reference. The linked JSON supplies the concrete input and output for this page.
What recorded result comes from this exact sample formula?
For the formula IFNULL([amount], 0), the published 8-row input has 8 recorded result rows. These are xmetric sample-example results; they do not establish native Tableau or Power BI parity, workbook coverage or corpus-wide compatibility.

How can I run this example on my own CSV?
Choose or drop one CSV into the live panel, match fields when the Tableau view requires mappings, and use the raw column names or mapped calculation names in that Tableau formula. Mapped names take precedence if names differ only in capitalization or collide. SQL and DAX use your actual column names. Choose Row calculation to write a new Tableau formula on the raw columns. Opening a CSV alone does not calculate a result; select Run formulas to evaluate the current rows. The panel is a progressive enhancement of the formula and recorded example already present in this HTML.
How do Tableau, DuckDB SQL and scalar DAX differ in this example?
Tableau formulas use the shown field types and view settings. DuckDB SQL reads a table named input; xmetric’s Power BI scalar DAX evaluator reads one table named Sales. Each formula runs independently, so successful execution alone does not establish equivalence.
| Language | Formula supplied on this page | Execution and limitation |
|---|---|---|
| Tableau | IFNULL([amount], 0) | xmetric’s Tableau calculation and view services use the supplied rows. LOD view grain and table-calculation addressing or partitioning affect results; a CSV does not import hidden workbook calculations. |
| DuckDB SQL | SELECT coalesce(amount,0) AS result FROM input | DuckDB compiled to WebAssembly executes the entered query over input. Snowflake, BigQuery and other dialects are not executed by this editor. |
| xmetric Power BI scalar DAX | No scalar DAX measure is supplied for this page. | xmetric evaluates one scalar measure over Sales. A CSV does not supply relationships, hidden measures or a multi-table Power BI model. |
What else do people ask?
Can xmetric chart this CSV?
This page’s panel returns formula-result rows. Open the xmetric browser app to create a chart from your CSV. The calculation shown here is IFNULL([amount], 0); choose dimensions and measures for the question you want to answer.
My client sent a .pbix and I’m on a Mac. Where do I open it?
Open the Power BI Desktop .pbix file in the xmetric browser app. Workbook features determine support. This formula panel accepts CSV or editable JSON rows and evaluates a scalar DAX measure over Sales; it does not import workbook relationships or hidden measures. Opening reads locally; an explicit Save uploads.
