I will clean and prepare llm training data jsonl CSV with ai cross verification

Are you building an LLM, RAG system, or fine-tuning project, but your training data is a mess? Duplicate rows, inconsistent field names, empty values, malformed JSON these don't just slow down training, they silently degrade your model's output quality.

I clean and prepare training datasets so they're ready to feed directly into your pipeline. My pipeline handles JSONL, CSV, XLSX, and even messy exports from Notion, Excel, or scraped sources. Every cleaning operation is logged you get a report showing exactly what was changed, nothing hidden.

Here's what makes this different:

Multi-model AI cross-verification on Standard/Premium two AI models review the cleaned data independently, and discrepancies are flagged for you

Schema preservation I clean the data, I never touch your field names or structure

Operation audit trail every dedup, every normalization, every removed bad row is documented

What you get:

1. Cleaned dataset in your requested format

2. A cleaning report showing what was done

3. Free 1-round revision

Send me a sample of your data first if you're unsure I'll tell you exactly what needs cleaning before you order.
