Export Data to XBRL
Once your report is ready and valid, you can generate an XBRL instance file. To do this, click Export XBRL in the add-in ribbon. By default, instance files are saved with a .xbrl extension. If you need the exported file to have another extension (for example, .xml), type the file extension in the Export dialog box.
During the export, data is automatically validated. Any errors, inconsistencies and warnings are reported on the screen after the export finishes. For more information, see The XBRL instance file is created even if the data is not valid. However, such report instances are not valid for XBRL submission. For more information, see Validate Data.
For tips on how to avoid data formatting errors, see Enter Data. Note, however, that not all XBRL validation errors might be related to incorrect formatting. Some errors might occur because entered data does not meet the XBRL validation rules applicable to the report you are filing. For more information about XBRL validation rules, see XBRL US Work In Process Taxonomy 2016 Preparers Guide.
