About RomitCSV
RomitCSV brings practical tools for working with CSV files together in one browser-based workspace. View a table, edit rows, clean duplicate data, validate a file, or convert it for another workflow.
The tools are designed for everyday data tasks, with focused pages for common operations and clear controls for importing and exporting files.
Everyday CSV work, in one place.
CSV files move data between spreadsheets, databases, and applications. RomitCSV collects tools that help with the steps around that work: previewing a file, making edits, checking its structure, removing duplicates, combining files, splitting large files, and converting between formats.
Choose the tool that fits your task, review the result, and download it when it is ready.
Pick a tool for the job.
Open CSV data in a table, search and sort records, or make edits before exporting the result.
Remove duplicate rows, validate structure, merge files, or split a large dataset into smaller parts.
Move between CSV, JSON, Excel, PDF, and SQL formats using the dedicated converter pages.
Column names, delimiters, empty values, and nested data can affect a conversion. Check the preview and use the output that fits the receiving tool.
Your file stays in your browser.
RomitCSV tools process input in the browser. Some features use browser libraries for file formats such as Excel or PDF. Avoid using any online tool with sensitive data unless it is approved for your workflow.
