The Data & Spreadsheets Lab is a comprehensive workspace for data analysts, financial planners, and software developers who need to transform and clean structured data without the risks of cloud uploads. Whether you are converting complex JSON API responses to spreadsheet-ready CSV files or cleaning up messy spreadsheet exports, our tools ensure that your raw data stays entirely within your local browser environment.
Industrial-Grade Data Transformation
Seamlessly move data between CSV, JSON, and XML formats. Deduplicate rows, clean up cell formatting, and consolidate multiple Excel workbooks into a single file with one sheet per source — all processed locally in your RAM to handle datasets up to 500MB. Specialized formatters and cleaners for SQL and XML make it easy to normalize raw data before integrating it into your production pipelines.
Formula AI and SQL Query AI are on the roadmap as server-assisted tools — currently marked "Coming Soon" until traffic justifies the ongoing API cost of running them.
