# Time-Series Matrix Transformation "Time-series matrix transformation" is a feature that transforms records stored in a related list of the Salesforce object from list form to matrix form, using a time-series field as an axis, and align them horizontally as same as the fields in the original Salesforce object in the sheet. In addition, inputted/updated data on the sheet is automatically transformed inversely from matrix form to list form when saving in Salesforce, which makes it possible to establish user-friendly data entry while maintaining the optimal database structure for reporting. {% hint style="success" %} Your organization must be enabled the "Matrix Transformation Option" to use this feature. If you wish to use it, please let us know to the sales representative in charge. {% endhint %} ## [Overview](https://docs.mashmatrix.com/mashmatrix-sheet/functions_advanced/time_series_matrix_transformation/overview) ## [Add Matrix Column](https://docs.mashmatrix.com/mashmatrix-sheet/functions_advanced/time_series_matrix_transformation/add_matrix_column) ## [Change Matrix Column Setting](https://docs.mashmatrix.com/mashmatrix-sheet/functions_advanced/time_series_matrix_transformation/change_matrix_column_setting) ## [Show / Hide Column](https://docs.mashmatrix.com/mashmatrix-sheet/functions_advanced/time_series_matrix_transformation/show_hide_column) ## [Add Child Columns](https://docs.mashmatrix.com/mashmatrix-sheet/functions_advanced/time_series_matrix_transformation/add_child_column) ## [Delete Child Column](https://docs.mashmatrix.com/mashmatrix-sheet/functions_advanced/time_series_matrix_transformation/delete_child_column) ## [Format](https://docs.mashmatrix.com/mashmatrix-sheet/functions_advanced/time_series_matrix_transformation/format) ## [Limitations](https://docs.mashmatrix.com/mashmatrix-sheet/functions_advanced/time_series_matrix_transformation/limitations)
