marta-duo is a Google Sheets editor add-on that exports Markdown tables

There are two files in this duo:

• Code.gs: provides the server-side logic, building a Marta object
• Sidebar.html: provides the client-side processing and download of the markdown text file

The purpose of this Google Sheet Add-on is performance and simplicity.

Unlike many other Markdown table exporters for Google Sheets, marta-duo will not timeout for very large tables.

To this point, the first test spreadsheet (test1.xlsx) has six (6) columns and one-thousand (1000) rows.

While it may take a while on some machines, the entire markdown table does indeed export (on tested machines).

Performance metrics and unit tests follow.
