NetSuite SuiteScript 2.0 export data to Excel file(xls)

In NetSuite SuiteScript, We usually do/implement export data to CSV, that's straight forward:

1. Collect 'encoded' string to Array for column, join them with comma ',' to be a string.
2. Collect each line's data same as column to push to the Array.
3. Join all the Array data(include column row and all data rows) with '\n\t' to a big CSV string.
4. Save the CSV string as file content then store it to file-cabinet, or write them directly in SuiteLet as a output.

Today I am going to talk about export custom NetSuite data to EXCEL file(file suffix is .xls)

1. Prepared XML header string.  Put in styles as desire, and workbook -> worksheet -> table
2. Concat to put in dynamic cell data.  So we got whole well formed xml string.
3. nlapiCreateFile(SuiteScript 1.0) or file.create(SuiteScript 2.0) put in encoded xml string to create a Excel file.
4. Store the file to filecabinet or set it as output of a SuiteLet(so directly download it)

Sample in SuiteScript 2.0:
