The product data consists of 2 ZIP files (7z) with data of Migros products in JSON format: /products/products_de.7z for product data with German texts, whereas the file /products/products_en.7z contains the product data with English texts, as far as there are English texts available. Mostly, when no English text is available, the texts are in German as a fallback.

Each file within the ZIP file represents the data for one product.
The filename is the Migros article number of the product.

Model Structure

The structure of the JSON in each file is defined in the file openapi.yaml as an OpenAPI specification.
You can visualize this file on https://editor.swagger.io/ if you like.

Not every product has all the fields described in the specification.
There might also be fields in the specification which no product has set.
 

CO₂ Data

Most food products have CO₂ data. Those data can be found in the object «co2_compensation». The value of «co2_compensation.kg_co2» tells you how much CO₂ emmissions have been caused by this product for production, transport and packaging. The field «co2_compensation.kg_co2_compensation» has the same value, unless the product got paid to offset the carbon footprint.

Data for M-Check sustainability scale

Every food product from a Migros-owned brand has some M-Check sustainability data. Those data can be found in the object «m_check2», and it includes its CO₂ footprint, including the CO₂ percentage through production, packaging and transportation. Additionally, it also contains an "animal welfare" rating. 

Here is a visual representation of those data:

Each file is a sample of the sales of one month.

Each file contains 10 columns:

• `YYYYMM`: reflects the filename and is year and month
• `KundeID`: anonymised household number
• `WarenkorbID`: a per-file, per-household sequence number
• `ProfitKSTID`: shop ID

• `ArtikelID`: Migros product number
• `Menge`: contains the amount bought: This might be in pieces or kilogram, depending on the article (meter or square meter are possible too but both are uncommon).
