We have a form hooked up to a Google Spreadsheet and it seems to be working well and capturing responses.
However, the column headings are not all useful - some are empty where a field in the form does not have a label (for example a compound "name" field with first and last fields but only a section label), and some columns with extra long text from a long label.
Is it safe to edit column headings (for the examples above to add a column label where there is currently no label, or shorten a long label)? Will this "break" the integration with the form? Obviously we would be careful not to add, remove or rearrange columns, just edit the first row.
