# Transform table

A [transform table](../cards-transform-table/index.md) is a local table used for flexible, low-scale analysis. It can be used for a number of different workflows in Quiver including:

* Converting between different data types.
* Joining and aggregating objects
* Editing tabular data in-line
* Deriving properties, and then performing operations on those derived properties such as filtering and plotting
* Performing batch time series operations

For a complete list of transforms available in transform tables, consult the [index of transform table transformations](../cards-transform-table-index/index.md).

Transform tables handle certain computations and visualizations differently than object sets. For details on property type stringification, categorical chart behavior, and pivot table dimension handling, see [transform table computation differences](../transform-table-computation-differences/index.md).

## Input type

Object set, transform table, event set, dataset, Dataset SQL, categorical chart, pivot table, time series chart, Ontology SQL, number array, string array, Boolean array, time array
