Beautiful tools for ugly data
A growing set of focused utilities for JSON, CSV, and messy real-world data. Each tool is designed like a product, not a throwaway form.
JSON to CSV Converter
Convert nested JSON, API responses, mixed arrays, and object-heavy payloads into a clean CSV with row node detection, selective flattening, and advanced parsing controls.
CSV Diff Tool
Compare two CSV files online, match rows by id or email, detect added, removed, changed, and unchanged rows, and download a structured diff CSV.
CSV Rows Splitter
Split multi-value cells into separate rows. Upload a CSV, choose the column and delimiter, and expand tags, emails, or phone numbers into one value per row.
CSV Splitter
Split a CSV by rows, file size, column values, rules, or date ranges. Preview the output, keep only the columns you need, and download the result as CSV or ZIP.
