DataFixer scans your CSV or Excel files, finds the mess, and helps you fix it visually. Every change previews instantly and can be undone. Your data never leaves your computer.
Extra spaces, duplicates, mixed date formats, inconsistent phone numbers — cleaning it by hand wastes hours every week.
Hand-editing columns, hunting for duplicates, and writing fragile formulas — one wrong cell and the totals silently lie.
Leading spaces, blank rows, duplicated records, dates in ten formats, phones with and without country codes.
Python, Pandas, awk — powerful but slow to set up, and risky when a one-off clean-up becomes a permanent pipeline.
From automatic problem detection to fine-grained manual control — cleaning is a visual, reversible workflow.
DataFixer scans your file and flags extra spaces, empty rows, duplicates and mixed formats — fix what it can in one click.
Add steps one by one — trim, de-duplicate, fill, format, split. Each step previews instantly and can be undone (Ctrl+Z).
Dates, phone numbers, text case, numbers, columns and more — 18+ operations covering the clean-ups people actually need.
See exactly what changed — old values struck through beside the new ones — so you never clean blind.
CSV, Excel and JSON, with encoding handled for you. Save a flow and replay it on next week's file.
