CloudExtend Excel for NetSuite masks the NetSuite internalID for picklist fields such as company name, item, etc. with your data by inserting a line break into a row. This means for any given row that is expanded you will also see the internal ID for certain fields expressed as [[nnnn]].
Customers that want to remove the reference to the internalID for reporting purposes can easily remove it by following the steps below.
Load your template
Download your data
Insert a column anywhere in the template being sure not to add any value in Row 1 (it's fine to change the name of the column from ColumnN to something more descriptive in Row 2).
Use a formula to lookup the field and only import the characters to the left of [[.
=LEFT(A1,FIND("[[",A1)-2) is an example formula that assumes the field you want to remove the brackets from is in cell A1.
Excel should automatically copy your formula to the bottom of the table column and your new column will have just the value for your field without the [[nnnn]].
Pro tip - create/record a macro that you can run on demand that inserts the column and then inserts the formula as well. Moving forward running the macro will be super fast. See this article for more information.
