About me
I clean and validate CSV, Excel, JSON, PDF, and ecommerce export data.
I help with deduplication, merging, reconciliation, Shopify and WooCommerce import preparation, format conversion, and repeatable Python or Excel automation.
Every project starts with a clear scope and measurable acceptance checks. For larger jobs, I recommend a representative sample first. You receive the agreed files plus concise notes explaining changes and exceptions.
Share the source format, target output, approximate volume, deadline, and an anonymized sample.
