The import of data into PrestaShop is a very common need but not always an easy process. Let's highlight what works and not.
Limits of importing data with PrestaShop
Yes it is possible to import a csv with PrestaShop. But if you read these lines, I imagine that like many others, you faced some if not all of the problems posed by this tool. I will mention only a few:
It crashes often with a 500 error or a time out when trying to import a few hundred lines.
It can not handle formats other than CSV (which is not a real standard).
It's a little easier since PrestaShop has integrated a column mapping tool, but the requested format remains complex, as for example for attributes. This often requires having to manually rework the files provided by wholesalers.
Many bugs, like productd created without an url rewritten, all the products that are stored in the home category, categories that disappear, etc.
No flexibility, it is always the entirety of the lines of the file which are imported. For example, you can not validate the settings by importing only the first line for testing.
Only ids and references can be used as key. it is missing names, supplier reference, ean and upc barcodes.
Aberrations that will eventually slow down your PrestaShop store. For example, the import of specifications (or features), generate hundred of custom features, instead of a few shared features. For example, if you have 10,000 products with 5 common features, that's 50,000 lines added to your database, whereas 5 would have been enough.
Complex to automate, with the obligation to go through CRON tasks.
It's slow, or very slow ...
Fortunately there is another solution that solves all these issues ...
___________The benefits of using Merlin Backoffice ® import addon ___________
Process .CSV or Excel files of any size
You will never encounter a time-out problem because the software optimizes in real time the size of the SQL queries sent to the server.
The record to date is a file of 360,000 product sheets imported at one time by a car parts seller.
For very large files, which can crash Windows, it is possible to ask the module to split the processing of the file in packets of lines (for example 8000).
Fast imports, perfect for daily updating of prices and stocks.
The import speed is limited mainly by the server and the network and is proportional to the number of columns to process.
You have a classic shared server: the average time is 0.3s per line.
You have a dedicated server: the speed record, made every day by one of our customers on its dedicated server, is 0.04s per line. Only 7 minutes each night to automatically import or update prices and quantities of 10,000 new products.
Reliable and secure data transfers.
You have the freedom to encrypt queries or not.
The addon script checks the import success of each line. You can export the import status report.
You decide which lines to import or not, which column to process or not. You can test safely on a few lines without having to modify the file.

You would like to import only a few lines? use the automatic filters to exclude the other lines.
Some data of the file are not correct? hop, use MagicEdit directly from the interface to bulk correct the data without opening the file.
Ask the program to pick up the listing on your wholesaler's server.
Ask Merlin Backoffice to automatically disable, hide or delete stock of obsolete products.
The file contains only your purchase price? indicate the desired margin and the module will compute and import for you the optimum selling prices.
