What data cleaning operations does FileHop support?
FileHop supports remove duplicates, sample rows, per-column filters in the table view, Find & Replace and row and column edits in the sheet editor, and format conversion. Sheet editing works up to 100,000 rows; larger files open read-only.
How is this different from Excel's data cleaning?
FileHop opens large CSV and Parquet files that Excel can't, works completely offline with no upload, and keeps data 100% private. Excel has far more editing tools for small files.
Can I clean files larger than Excel's 1M row limit?
Yes! FileHop handles CSV files with billions of rows. Clean 10M, 50M, or 100M+ row files that Excel can't even open. Perfect for database exports, log files, and enterprise datasets.
Is this a replacement for Alteryx?
No, not for pipelines. FileHop covers a few everyday jobs (remove duplicates, filter, find and replace, convert) for free. It has no workflow builder. Alteryx costs $5,195-50,000/year and is built for repeatable enterprise pipelines.
What file formats are supported?
Clean CSV, TSV, Excel (XLSX), and Parquet files. Convert between formats, including JSON, from the Data Tools menu. .xls opens read-only, so convert it to .xlsx first.
Can I batch clean multiple files?
Yes, for remove duplicates and format conversion. Select your files and run the same operation on all of them. Each file is written separately.
Will my original files be modified?
Remove duplicates and format conversion create new files and leave originals untouched. Sheet editor changes go to the same file when you Save, so use Save as new if you want to keep the original.
Is data cleaning free?
Completely free with unlimited files and rows. No file size limits, no watermarks, no credit card required.
