Step 1: Identify the Compression Format

Taobao data can be compressed using various formats, including ZIP, RAR, 7z, and GZ. To decompress your Taobao data, you first need to identify the compression format. This information can typically be found in the file name or in the "Description" field of the Taobao download page.

Step 4: Extract the Encrypted File (for CSV and TSON data)

Step 5: Convert the Encrypted File (for TSON data)

Once you have extracted the encrypted TSON file, you need to convert it to a JSON file. Here's how:
In a terminal window, navigate to the directory containing the extracted file.
Enter the following command, replacing "" with the name of the extracted file: tsojson

Step 6: Process the Decompressed Data

Once the data is decompressed and extracted, you can process it further depending on your needs. This may involve converting the data to a different format, cleaning it, or analyzing it.
