# Lookup Table

In some systems there may be non-numeric data that needs to be fed into a time series data model. In Koios, we treat all data fed in to the model as normalized floating point values. This can pose an issue when the value is a string some other datatype incapable of being coerced to a floating point number. Our solution is to allow the user to create an enumeration table to “lookup” values.

To enable this feature, go to the `General` settings using the tag’s detail dropdown, and expand the `Advanced Options` menu at the bottom of the form. From here, check the box that says `Use Lookup Table`.

Once that is done, the `Lookup Table` tab will appear for this tag.

In the case above, the tag is looking for a string value of “On” or “Off” coming in as an input. This is then being converted to the output of 0 or 1. These fields are editable and expandable into large lookup tables for complex enumerations. By clicking `+ Add Row`, you are prompted with this popup where you can add new rows. To delete rows, click on one and select `Delete Row`.
