1. A method, comprising: at one or more computing devices comprising one or more processors and storage media storing one or more computer programs executed by the one or more processors to perform the method, performing operations comprising: in response to detecting a semantic organization event in a first graphical user interface content-view of a spreadsheet, determining whether semantic organization data associated with a first set of data cells of the spreadsheet should be stored, wherein the semantic organization data describes how the spreadsheet is organized; wherein the first set of data cells includes a plurality of columns; wherein the plurality of columns of the first set of data cells includes a plurality of data cell values; wherein the spreadsheet includes a header that collectively groups the plurality of columns within the spreadsheet; wherein the header and the plurality of data cell values are content input into the spreadsheet; wherein the semantic organization data includes the header; in response to determining that semantic organization data should be stored, storing semantic organization data associated with the first set of data cells; generating a preview thumbnail image based on the semantic organization data; displaying a graphical user interface semantic-view of the spreadsheet, wherein the graphical user interface semantic-view comprises the preview thumbnail image corresponding to the first set of data cells; wherein the preview thumbnail image displayed includes display of the header that collectively groups the plurality of columns within the spreadsheet; and in response to detecting a selection of the preview thumbnail image corresponding to the first set of data cells, navigating to a display of the first set of data cells in a second graphical user interface content-view of the spreadsheet.
