Instantly inspect and audit CSV and Excel datasets in browser memory. Computes null percentages, distinct value cardinality, numeric min/max/mean/median, and inferred SQL types.
Convert CSV, TSV, and Excel spreadsheets into clean GitHub-flavored Markdown tables with automatic delimiter detection, numeric right-alignment, and pipe escaping in browser RAM.
Identify and purge duplicate rows across whole records or custom composite key columns with whitespace normalization, case-sensitivity toggles, and detailed audit statistics.
Reconcile two CSV spreadsheets side-by-side by primary key identifier. Pinpoint added, deleted, and modified rows with cell-level highlights and exportable delta audit reports.
Sanitize and mask sensitive personally identifiable information (PII), names, emails, phone numbers, and IDs in CSV datasets locally in RAM before sharing with AI models or third parties.
Convert between Comma (CSV), Tab (TSV), Semicolon (European Excel), and Pipe (PSV) delimiters with auto-detection, RFC 4180 quote preservation, and zero data corruption.
Convert CSV spreadsheets and tabular files into optimized, syntactically escaped SQL INSERT statements for PostgreSQL, MySQL, SQLite, and BigQuery with type inference and batch chunking.
Data Quality Auditing, Missing Value Ratios, Numerical Distribution Metrics & SQL Type Detection
Before ingesting datasets into machine learning pipelines, relational databases, or BI tools, data engineers must audit data quality (missing values, unexpected types, outliers). Uploading unverified customer or medical datasets to cloud profilers introduces compliance liability under GDPR and HIPAA. VedKit executes 100% In-Browser Memory Profiling, generating detailed data quality metrics without a single byte leaving your machine.
For every column in your CSV or Excel spreadsheet, the engine computes:
N/A values to assess completeness.BOOLEAN, INTEGER, DECIMAL, DATE, TIMESTAMP, or TEXT based on sample value distribution.Quickly detect silent data corruption:
"Active" vs "Active ").YYYY-MM-DD vs DD/MM/YYYY).How Tabular Dataset & CSV Profiler Studio processes files securely inside your device memory
Every byte of your file is loaded directly into browser ArrayBuffers. Data is processed in volatile sandbox memory and flushed immediately when you close or refresh this tab.
Calculations and image matrix transformations leverage client-side GPU / Canvas2D engines for zero-latency output without server queuing or rate limits.
Generated files strictly follow international ISO specifications (JPEG JFIF, PDF 1.7, Web Crypto API) to guarantee acceptance on all official portals and banking systems.
Quick 4-step guide for instant results
Drop any .csv, .tsv, or .xlsx file (up to 100MB+) into the secure profiler dropzone.
The engine parses rows, analyzes lexical distributions, and computes column statistics in local RAM.
Review per-column null percentages, unique value counts, sample values, and numeric min/max/median.
Copy the inferred SQL DDL schema or download the comprehensive data profiling report.
