Nothing in HL.
I do have a Google Spreadsheet I did a couple years ago. It generates magic items that a town may "Sell" based on some stats. It includes the Ultimate Equipment Guide for items/abilities and being a spreadsheet, can be modified.
It's not the "Prettiest" but gets the job down. I have a few "Shops" set as examples (that I use in my own game) and they are set to auto-generate every Tuesday using Google Scripts. I use the "charts" as "permanent links" inside my Forums and MapTool for updated displays/lists of said shops.
It may not be perfect but feel free to copy/reuse/edit/enhance.
