About DataBench
DataBench is a free, browser-based workbench for cleaning and reformatting structured data. It's built for analysts and data scientists who need to quickly validate a JSON payload, fix a messy CSV export, tidy up a SQL query, or convert between JSON and CSV without installing anything or uploading files to a server.
Every tool runs entirely client-side — your data never leaves your browser. Pick a tool from the left to get started: the JSON formatter validates syntax and pinpoints errors by line, the CSV cleaner trims whitespace and removes empty or duplicate rows, the SQL formatter standardizes keyword casing and indentation, and the JSON ⇄ CSV converter handles both directions automatically.
