Amazon ASIN Merging and Catalog Update

I have several stand-alone listings on Amazon that need to be merged with their respective parent ASINs.

Your tasks will involve:
- Downloading my entire catalog from Amazon.
- Merging the standalone listings and organizing them by color variations.
- Uploading the fixed catalog back to Amazon.

Please note:
- All ASINS are live on FBA, so you must be familiar with the correct procedures and restrictions.
- SKUs cannot be changed.
- Only color variations need to be considered, as well size.

The size categories to be used are:
- Numeric Sizes (e.g., 6, 8, 10)

The catalog file should be in:
- CSV (.csv) format.

Ideal skills for this project include:
- Expertise in Amazon Seller Central
- Proficiency in catalog management
- Familiarity with FBA procedures
- Experience with ASIN merging

Thank you.
