Reusing Open Food Facts Data
Open Food Facts data is released as Open Data: it can be reused freely by anyone, under the Open Database License (ODBL). While this page is related to practical reuse, you must really be aware of rights and duties provided by the Open Database License (ODBL).

Where is the data?
You'll find different kind of ways to get the data.
Looking for a selection of products?
Then use the advanced search. The Open Food Facts advanced search feature allows to download selections of the data. See: https://world.openfoodfacts.org/cgi/search.pl
When your search is done, you will be able to download the selection in CSV or Excel format, just give a try!
Looking for the whole database?
The whole database can be downloaded at https://world.openfoodfacts.org/data
It's very big. Open Food Facts hosts more than 1,400,000 products (as of July 2020). So you will probably need skills to reuse the data.
You'll be able to find here different kinds of data.
The MongoDB daily export
It represents the most complete data; it's very big and you have to know how to deal with MongoDB.
The JSONL daily export
While still undocumented, there is a daily export of the whole database in jsonl format. It represents the same data as the MongoDB export. It's very big! More than 14GB uncompressed.
You can find it at https://static.openfoodfacts.org/data/openfoodfacts-products.jsonl.gz
The CSV daily export
It contains all the products, but with a subset of the database fields. This subset is very large and include main characteristics (EAN, name, brand...), many tags (such as categories, origins, labels, packaging...), ingredients and nutrition facts. Thus, it is generally fitted to the majority of usages. It's a 2.3GB file (as of April 2020), so it can't be opened by Libre Office or Excel with an 8GB machine.
How to reuse?
CSV daily export
csvkit is a very efficient tool to manipulate huge amounts of CSV data. Here are some useful tips to manipulate Open Food Facts CSV export.
Selecting 2 columns. Selecting two or three columns can be useful for some usages. Extracting two columns produce a smaller CSV file which can be opened by common softwares such as Libre Office or Excel. The following command creates a CSV file (brands.csv) containing two columns from Open Food Facts (code and brands). (It generally takes more than 2 minutes, depending on your computer.)
$ csvcut -t -c code,brands en.openfoodfacts.org.products.csv > brands.csv
Selecting products based on a regular expression. csvkit can search in some specified fields, allowing to make powerful selections. The following command creates a CSV file (selection.csv) containing all products where the barcode (code) is beginning by 325798 (
$ csvgrep -t -c code -r "^325798(.*)" en.openfoodfacts.org.products.csv > selection.csv
The following command creates a CSV file (calissons.csv) containing all products where the category (categories) is containing "calisson".
$ csvgrep -t -c categories -r "calisson" en.openfoodfacts.org.products.csv > calisson.csv
Import CSV in PostgreSQL
See this article: https://blog-postgresql.verite.pro/2018/12/21/import-openfoodfacts.html (in french, but should be understandable with Google Translator).
Import CSV to SQLite
The repository foodrescue-content contains Ruby scripts that import Open Food Facts CSV data into a SQLite database with full table normalization. Only a few fields are imported so far, but this an be extended easily. Data imported so far includes:
- barcode number
- product name
- product categories
- product countries
- full categories hierarchy imported from the
There are some articles dealing with using Python language to explore Open Food Facts data.

Python notebooks are great to learn Open Food Facts data, as they mix code and results together:
- Find dozens of python notebooks on Kaggle
For people who have R stat skills, there are more than 50 notebooks from Kaggle community.
JSONL is a huge file! It's not possible to play with it with common editors or common tools. But there is some command line tools that allows interesting things, like jq.
- start decompress the file (be carreful => 14GB after decompression):
$ gunzip openfoodfacts-products.jsonl.gz
- work on a small subset to test. E.g. for 100 products:
$ head -n 100 openfoodfacts-products.jsonl > small.jsonl
You can start playing with jq. Here are examples.
$ cat small.jsonl | jq . # print all file in JSON format
$ cat small.jsonl | jq -r .code # print all products' codes.
$ cat small.jsonl | jq -r '[.code,.product_name] | @csv' # output CSV data containing code,product_name
Then you can try on the whole database:
$ cat openfoodfacts-products.jsonl | jq -r '[.code,.product_name] | @csv' > names.csv # output CSV file (name.csv) containing all products with code,product_name
If you don't have enough disk place to uncompress the .gz file, you can use zcat directly on the compressed file. Example:
$ zcat openfoodfacts-products.jsonl.gz | jq -r '[.code,.product_name] | @csv' # output CSV data containing code,product_name
