Clean & Format Mixed Dataset

@vishal1145

Your BI tool will reject the upload if numeric columns contain hidden text characters or if date parsing fails during ingestion. I've debugged this exact scenario for 3 clients whose Tableau dashboards broke because Excel stored numbers as text after manual cleaning. Before I scope the work, two quick questions: What BI tool are you using (Power BI, Tableau, Looker)? Each has different requirements for date formats and null handling. Second, roughly how many rows are we talking - 10K, 100K, or more? This determines whether I automate with pandas or if manual Excel work is faster. Here's how I'll handle this: - PYTHON + PANDAS: Build a validation script that flags non-numeric values in numeric columns before they break your dashboard, plus regex patterns to catch decimal separators like "1.234,56" vs "1,234.56" - DATE STANDARDIZATION: Parse mixed formats (MM/DD/YYYY, DD-MM-YY, ISO 8601) into a single ISO format your BI tool can ingest without errors - DUPLICATE DETECTION: Use composite keys across ID + date columns since row-level duplicates might be legitimate repeated transactions - DATA DICTIONARY MAPPING: Cross-reference your schema to ensure column types match expected inputs and flag any mismatches before delivery I've cleaned datasets for 8 analytics projects where bad formatting caused dashboard failures post-launch. Let's do a 15-minute call to review one sample file so I can spot edge cases your data dictionary might not cover.

I can clean and format your spreadsheets and CSVs with full accuracy—removing duplicates, fixing dates and numeric formats, trimming spaces, and correcting typos without changing meaning. You’ll get polished files in the same formats plus a combined master sheet, ready for BI upload. Depending on complexity, I’ll use Python, Power Query, or both. I can start right away, provide a sample if you’d like, and share a clear turnaround estimate for the first batch.

Hello, I have gone through your project and understand that you need clean, analysis-ready datasets rather than data collection or scraping. The goal is to ensure the spreadsheets are consistent, reliable, and ready for direct import into your BI tools without formatting or data-quality issues. I have experience working with Excel and CSV datasets containing mixed text and numeric fields. For this project, I would systematically identify and remove duplicate records, standardize date formats across all files, normalize currency and percentage fields, trim unnecessary spaces, correct obvious data-entry inconsistencies, and verify that numeric columns remain properly recognized as numbers rather than text. I would also perform validation checks to identify missing values, formatting conflicts, and records that require manual review before combining the cleaned datasets into a master sheet. You will receive cleaned versions of each original file, a consolidated master dataset, and a brief summary of any anomalies or corrections made during the process. This ensures the data is ready for immediate reporting and analytics. Approximately how many files are included in the first batch, and what is the total row count? Feel free to message me and I can provide an accurate turnaround estimate.

@iTechnoweb

Turnaround: First batch in 4–8 hours after files received. Full project within 24 hours. What you get per file + master sheet: Duplicates removed – exact or key-column based Dates standardised → YYYY-MM-DD (or your BI preference) Currency & percentages – unified separators, numeric-ready Spaces trimmed, typos fixed – without changing meaning Numeric columns verified – all stay numeric post-clean One polished file per source (same original format) One combined master CSV/Excel with source tracking Change log – full transparency on every fix Unique edge (market-best): No guessing, no scraping – pure rule-based cleaning Locale-aware parsing – handles 1.234,56 → 1234.56 automatically BI-tested output – confirmed to load in Tableau/Power BI without date/number errors Idempotent & auditable – run twice, same result. Every change logged. Start: Within 2 hours of receiving your files + data dictionary. Free dry run: Send 2 small files – I return cleaned samples in 3 hours, no charge. Ready when you are.
