CSV Editor

CSV Wrangler is a free CSV editor for inspecting, cleaning, deduplicating and exporting CSV files in your browser.

Your data never leaves your device.
No account, no upload, no limits.

Open a CSV file

Drag and drop a .csv, .tsv or text file here or browse for one. Your file is read locally and never uploaded.

Try a 100 MB file, not just small ones. Large files open in streaming mode.
