CSV File Tools is a free browser toolkit for working with CSV and TSV data. Open and edit a table, sort and filter rows, validate CSV, clean values, merge or split files, and convert CSV to formats such as JSON, Excel and Parquet. No signup is required for the browser tools, and file contents stay on your device. Useful for checking exports and preparing data before an import.
Loam grounds AI in your actual data so it stops hallucinating numbers. Upload CSV, Excel, Parquet, or JSON, ask in plain English, and get answers computed from real rows with the query shown. Use Loam directly or connect from Claude, Cursor, or any MCP client.
