Upload your Excel or CSV file, clean it with 50+ one-click transforms, set validation rules, and export perfect data — no training required.
No signup required. No credit card. Works in your browser.
You open a spreadsheet with 10,000 rows. Half the emails are broken. Dates are in 5 different formats. Phone numbers have random spaces. You sigh and start cleaning. Manually. Again.
You Google "data cleaning tool" and find Alteryx. $433/month. Tableau Prep? $70/month. Your boss says "just use Excel." You die a little inside.
You finish cleaning. But did you miss something? Row 4,847 has an invalid postal code. Row 7,203 has a duplicate. You won't know until your report is wrong and someone notices.
Next week, same spreadsheet, same mess, same process. You clean the same columns the same way. Every. Single. Week. There has to be a better way.
Clean, reshape, and fix your data with one-click operations. Trim whitespace, remove duplicates, standardize dates, fix phone numbers, parse emails — all without writing a single formula. Just pick a transform. See the preview. Apply.
Excel Validator analyzes your columns and suggests validation rules before you ask. Email column? Email format rule applied. 15% nulls? Required field warning. You just click accept.
See every invalid row, every error type, every failed rule — organized, ranked, and exportable. Download clean rows separately from dirty ones. Share a validation report with your team.
Drag & drop your Excel or CSV file. Supports .xlsx, .csv, .tsv up to 1M rows.
Instantly see your data with column statistics, null counts, and data type detection.
Pick from 50+ transforms. Build a pipeline. See before/after preview in real-time.
Set rules per column — or accept smart suggestions. Required, format, range, custom regex.
Download clean data, error reports, and validation summaries. Excel, CSV, or clipboard.
Clean, reshape, and standardize data with 50+ one-click operations across 7 categories. Trim, deduplicate, regex replace, date parsing, number formatting, and more — all with instant preview.
Excel Validator analyzes your columns and suggests the right validation rules automatically. Accept with one click. Override when you need to. It's like having a data quality expert on call.
Save your transform + validation pipeline as a workflow. Load it next week with one click. Stop rebuilding the same process every Monday morning.
See distribution histograms, pattern detection, null analysis, and top values for every column — automatically. Profiling turns raw data into insights before you even start cleaning.
Every run is saved. Compare results over time. See if your data quality is improving or degrading. Reopen any past configuration and apply it to new data.
