Tips: Paste from Excel uses tab characters between cells and newlines between rows. Arrow keys move between cells when the grid is focused. Undo/redo applies to the whole sheet (add/delete row/column, load, trim, transpose, paste block).
About the CSV Editor
Upload a CSV, edit rows and columns in an Excel-like grid, then download the updated file for imports, product feeds, contact lists, and quick corrections.
Fix tabular data without a desktop spreadsheet
The grid is for targeted cell edits—names, IDs, categories, quantities—when opening Excel would be overkill for a small import fix.
Convert formats with CSV to JSON or JSON to CSV, pull sheets via Excel to CSV, check structure with the CSV Validator, or combine files in CSV Merge.
Fix import and feed sheets
Correct product imports, customer lists, inventory feeds, or seed data before uploading into another system.
Download the edited CSV
Save the updated table for the next import, marketplace upload, or reporting step.
Convert, validate, or merge
Continue with CSV to JSON, JSON to CSV, Excel to CSV, CSV Validator, or CSV Merge.
