Air-Gapped Data Wrangling Toolkit
In-browser SQLite analysis, table conversions, data visualization, and synthetic dataset generation
"Clean, convert, and query sensitive tabular datasets without uploading private spreadsheets to third-party clouds."
Data analysts and investigative journalists regularly handle sensitive CSVs, employee payroll data, financial balances, and confidential survey logs. Uploading these datasets to web-based converters or online BI dashboards is an acute security hazard that can violate GDPR and corporate data handling policies. The Air-Gapped Data Wrangling Toolkit executes all transformations locally: query tables using in-browser WebAssembly SQLite, generate publication-grade SVG charts, convert tables across formats, and create synthetic test data with complete privacy.
