CSV Editor
The universal upload editor accepts both CSV and Excel files and opens them in a full browser-based spreadsheet grid. You can inspect rows, edit cell values, add or remove columns, and export the updated file — useful when a conversion step produces data that still needs manual cleanup before sharing.
About the CSV and Excel to edited CSV or spreadsheet data format
CSV files are parsed with standard comma-delimiter rules, including support for quoted fields that contain commas. XLSX files are read with the SheetJS library, preserving multiple sheets and common cell data types. Exported files can be saved as CSV or Excel depending on what your downstream workflow requires.
Common use cases
- Fixing typos in a customer list exported from a CRM before importing it elsewhere.
- Removing blank rows and stray header lines from a CSV downloaded from an internal report.
- Reviewing a converted JSON-to-CSV output and adjusting column values before sending to a manager.
- Making quick edits to an Excel workbook on a machine where desktop spreadsheet software is not installed.
How to use this tool
- Upload your CSV and Excel file or paste the source content into the text box on this page.
- Click the convert button and wait for the browser to parse the input into consistent columns.
- Inspect the output preview — check row counts, column headers, and sample values before downloading.
- Download the result as edited CSV or spreadsheet data and continue with your spreadsheet, database, or reporting workflow.
Tips for best results
- Upload via drag-and-drop for faster workflow — the editor accepts files directly from your file manager.
- Use keyboard shortcuts (Ctrl+C, Ctrl+V, Ctrl+Z) for familiar copy-paste and undo behavior.
- After editing, export to CSV if the next step is another converter; use XLSX if the recipient expects Excel.
Common pitfalls
Complex Excel formatting, macros, and embedded charts are not preserved — the editor focuses on tabular data. Formulas are stored as their computed values, not as live formulas.
