DeepCleanCSV
Clean your messy CSV for ML & analysis in seconds
Clean your CSV for ML & analysis in seconds — also supports Excel. Automatically fix nulls, duplicates and wrong data types. No code, no formulas. Upload your file → automatic detection of problem columns → configure operations → download clean CSV or Excel + PDF report + change log. Built for data scientists, ML engineers and analysts. Reusable cleaning profiles for recurring datasets. Accepts any CSV separator. Free to start.
Every data project I worked on started the same way: an hour or more cleaning CSV or Excel files before touching any actual analysis. Nulls everywhere, duplicate rows, columns with mixed types. Boring, repetitive, error-prone.
I built DeepCleanCSV to solve exactly that. Upload your file, configure what to fix, and get a clean CSV or Excel + PDF report + change log in seconds. No code, no installation.
- Duplicate detection with case-insensitive option
- Type correction — keep-as-string for IDs, ZIP codes and phone numbers
- Text and encoding cleanup with row-level warnings for corrupted characters
- Numeric precision control per column
- Empty and constant column detection — remove each with an independent checkbox
- Reusable cleaning profiles for recurring datasets
- Built-in CSV or Excel viewer — paginated, searchable, no install needed
- CSV ↔ Excel conversion — upload one format, download the other
The hardest part wasn't the cleaning logic — it was making the tool simple enough that anyone, not just developers, could use it confidently.
Free to start. Would love to hear what you think.
