Bring in your data
Drag and drop a file, click to choose one, or paste CSV into the text area on the right.
Tune options and edit the table
Pick the delimiter, whether the first row is headers, quote mode, and BOM; edit cells in the grid and use the top bar to add rows or columns.
Export JSON, CSV, or XLSX
Live JSON and CSV previews appear below. Copy or download them, or save an Excel-friendly XLSX file.
When is this tool most helpful?
Whenever you need to tidy CSV from spreadsheets, switch delimiters, rename columns, fix cell values, or hand the same table to code as JSON and to teammates as XLSX—all in the browser.
Can I edit the table directly?
Yes. After parsing you get an editable grid: change header names and cell text, and add or remove whole rows or columns.
How should I choose a delimiter?
Start with auto-detect if you are unsure. Switch to comma, semicolon, tab, or pipe only when you know how the file was produced. The same choice is used for parsing and CSV export.
Why add a UTF-8 BOM to CSV?
Some spreadsheet apps and older systems read UTF-8 more reliably with a BOM, especially for non-Latin text. If characters look wrong after import, try exporting again with this option on.
Is my data uploaded to your servers?
No. Parsing, editing, and export all run locally in your browser; we do not receive your content on our servers.
