Once your report is ready and valid (see Validating Data), you can generate the XBRL instance file. To do this, click the tab, and then click Export to XBRL.
By default, instance files are saved as files with .xbrl extension. If you need the exported file to have another extension (for example, .xml), type the file extension in the Export dialog box.
While the XBRL instance is being created, a dialog box which informs you about the progress may be displayed for a short time.
During the export operation, data is automatically validated. Any errors, inconsistencies and warnings are reported on the screen after the export finishes.
The XBRL instance file is created even if data is not valid; however, such report instances are not valid for XBRL submission (see also Validating Data).
In case of invalid reports, the cell values that are XBRL incompatible are ignored and not written to the XBRL instance file. For tips on how to avoid data formatting errors, see Entering 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 the "XBRL US Work In Process Taxonomy 2016 Preparers Guide".
