Free 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. Made by the team behind Flookup.
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.
Streaming mode: browsing, filtering, sorting, analysis and export are available. Editing cells and transformations are disabled for very large files.
Need fuzzy matching for messy duplicates?
CSV Wrangler flags exact and near-duplicate rows. For full fuzzy matching, phonetic matching and AI-powered reconciliation inside Google Sheets, try Flookup Data Wrangler.
CSV Wrangler processes every file locally in your browser. Nothing is uploaded, tracked or stored by us. Sessions are saved in your browser only.
