Data fields in the API

This file describes the fields from the CSV and json export of the products in the Open Food Facts database.

See https://world.openfoodfacts.org/data for more information.

The file encoding is Unicode UTF-8.

CSV API

The character that separates fields is <tab> (tabulation).

JSON API

Status 0

This status indicates that the product can not be found { "status_verbose":"product not found", "status":0, "code":"32562641919" }

Generalities

  • fields that end with _t are dates in the UNIX timestamp format (number of seconds since Jan 1st 1970)
  • fields that end with _datetime are dates in the iso8601 format: yyyy-mm-ddThh:mn:ssZ
  • fields that end with _tags are comma separated list of tags (e.g. categories_tags is the set of normalized tags computer from the categories field)
  • fields that end with a language 2 letter code (e.g. fr for French) is the set of tags in that language
  • fields that end with _100g correspond to the amount of a nutriment (in g) for 100 g or 100 ml of product

nutrition facts

The nutrition facts are presented by multiple fields per nutrition fact. Each nutrition fact is presented by a key, i.e. "salt", "fat", etc. The fields can also be found in the taxonomy translation file.

The fields can have the following structure:

  • key_value (string) - the standardized value of a serving of 100g (100ml) for type key (eg in json: "salt_100g":"0.19");
  • key_unit (string) - the units used in the other fields (eg in json: "carbohydrates_unit":"g"). Possible values are "kg", "g", "mg, "µg", "l", "ml", "%" or "";

key_value and key_unit are what is entered by the user, or passed to the write api, with the "key" and "key_unit" fields.

  • key (string) - the value for the nutrition fact key (eg in json: "fiber":"0.5");

Then "key" is a conversion in the default unit of the field (kJ or g)

  • key_serving (string) - the value of a serving for type key (eg: in json "carbohydrates_serving":"5.82"). The size of the servig is found in the serving field;
  • key_100g (string) - the standardized value of a serving of 100g (100ml) for type key (eg in json: "salt_100g":"0.19");

And "key_serving" "Key_100g" are values for the serving size or 100g. One of them is equal to "key", the other is converted.

  • key_label (string) - a more user friendly text explaining the

Only the nutrition facts that are actually found on the packaging are present in the interface.
