# Dataset Card for UK Supermarket Time Series Data (Combined)

This dataset is a **consolidated version** of the [Time Series UK Supermarket Data](https://www.kaggle.com/datasets/declanmcalinden/time-series-uk-supermarket-data) originally shared by Declan McAlinden under the Apache License 2.0.  

It merges the **five original CSV files** (one per UK supermarket) into a **single Parquet file**:  
`base_retail_gb_snappy.parquet`

Listed UK supermarket, Sainsbury, ASDA, Tesco, Morrisons & Aldi

The data remains unchanged, but combining the files simplifies loading and analysis, especially for large-scale analytics and machine learning workflows.
