Large file upload and database modification for an existing Wordpress website


We have an existing website built on Wordpress that is used as a product search engine.

There are 1,300,000 products held in the database.

Users visit the site to check the latest price of a products. These prices products fluctuate daily.


The administrator keeps an excel spreadsheet of these prices and has to currently update the prices manually which is a time consuming process.


• Create a new page on the wordpress website

• This page should have a file upload box

• This file upload box should only accept .xls or .xlsx files

• This file upload box should only accept correctly formatted files.

• On upload any product data that has an existing entry in the existing product database should be overwritten with the new data and price.

o Products are compared by the “Product column” in the spreadsheet

• Any products already in the database that do not appear on the spreadsheet should remain unaltered.

• There could be 250,000 products on any spreadsheet to be uploaded at the same time.

• The upload shouldn’t time out or cause any load related issues on the server.

• Any issues with the upload should be handled with a user friendly error message.

• If the upload is to take some time there should be an indication of this for the user.

If you require any further details please ask.

Sample upload spreadsheet attached.
