Data Sources

A Data Source is your Excel model. It is the foundation for everything else in RuleX.

Adding a Data Source

Go to Data Sources in RuleX Admin and click Add Data Source (top right corner).

You can provide your model in two ways:

• Upload an Excel file: upload a .xlsx file from your computer.
• Import from Google Sheets: paste the URL of a Google Sheet. RuleX downloads it as an Excel file.

Give the Source a name. If your model uses date or datetime values, set the timezone. The timezone controls how date and datetime inputs are interpreted when the model runs.

Build status

After you save a Data Source, RuleX compiles it in the background. The Data Sources list shows the build status for each Source.

You can define a Schema against a Source once metadata has been built. It usually takes less than a minute to build the metadata. Endpoints are not available until the build is Completed.

Sources are immutable

Once created, a Data Source cannot be modified. If you need to update your model, upload a new Source and point your existing Schema at it. Your Endpoints continue working without any changes.

Cell constraints

Only static cells (cells that contain a value, not a formula) can be used as inputs. Formula cells are evaluated by RuleX at runtime and cannot be overridden from outside.

If you try to map an input to a formula cell, RuleX will reject the Schema. Plan your input cells as plain value cells before uploading.
