Using Excel and Google Sheets, I clean, organize, and structure data for immediate business use.
With over 10 years of experience in data operations and 260+ completed projects across different freelance marketplaces, I specialize in execution-heavy work where accuracy, consistency, and rule adherence matter more than speed or automation.
My core strength is transforming raw, fragmented, or ambiguous information into clean, structured datasets that are reliable, reproducible, and ready for decision-making.
What I Specialize In
Manual Data Research & Validation
• Cross-platform research and fact verification
• Evidence-based matching (URLs, references, documentation)
• Clear documentation of unresolved or ambiguous cases
• No assumptions — validation before inclusion
ChatGPT-Assisted Data & Content Work
• Prompt-based structured content generation
• Multilingual content creation (EN, ES, DE, FR, IT, HI, PT, ZH)
• Travel, company, entity, and descriptive dataset creation
• AI-generated outputs reviewed and formatted for consistency
• Large-scale structured data population using defined prompts
(Example: Built multilingual country summaries and structured datasets for ~200 travel destinations using ChatGPT + Google Sheets workflows.)
Data Normalization & Structuring
• Standardization using predefined naming rules
• Classification, tagging, confidence scoring
• Schema alignment and logical column design
• Accuracy-first approach — completeness never at the cost of correctness
Structured Data Delivery
• Excel & Google Sheets optimized for clarity and reuse
• Clean formatting, consistent schemas, logical organization
• Ready for analysts, developers, or publishing platforms
Document & Data Processing
• PDF to Excel/Word conversion
• Structured transcript collection
• Content organization with strict file naming conventions
Typical Projects I Handle
• AI-assisted content generation with structured validation
• Company reports download or collection
• Cross-platform listing research and identity matching
• Creator, company, or lead database building
• ESG & sustainability research datasets
• Manual data cleanup under strict written rules
Many projects start with fragmented spreadsheets or undefined data fields. I transform them into clean, structured, and reproducible datasets.
How I Work
• Follow written instructions exactly — no improvisation
• Use ChatGPT as a productivity tool, not a replacement for validation
• Cross-check outputs before delivery
• Maintain documentation and audit clarity
• Deliver organized, reproducible results
If you need careful execution, structured thinking, and dependable accuracy, I’m ready to support your project—whether it’s a one-time dataset or ongoing work.
Sincerely,
Juthika Das
