+## Excel Uploads
+
+Thanks to our pro license of [sheetJS](https://sheetjs.com/), we can support all versions of excel, large workbooks, and extract data extremely fast.
+
+The rules for data extraction are:
+
+* Scan the spreadsheet until a row is found with all the target columns (not case sensitive)
+* Extract data below that until the *first row containing a blank primary key value*
+
+This is incredibly flexible, and means:
+
+* data can be anywhere, on any worksheet
+* data can contain additional columns (they are just ignored)
+* data can be completely surrounded by other data
+
+A copy of the original Excel file is also uploaded to the staging area.  This means that a complete audit trail can be captured, right back to the original source data.

+When loading dates, be aware that Data Controller makes use of the `ANYDTDTE` and `ANYDTDTTME` informats (width 19).
 This means that uploaded date / datetime values should be unambiguous (eg `01FEB1942` vs `01/02/42`) to avoid confusion - as the latter could be interpreted as `02JAN2042` depending on your locale and options `YEARCUTOFF` settings.  Note that UTC dates with offset values (eg `2018-12-26T09:19:25.123+0100`) are not currently supported.  If this is a feature you would like to see, contact us.
