Spreadsheet Cleaner

About Spreadsheet Cleaner

The Spreadsheet Cleaner takes a messy CSV, XLSX, XLS or TXT file and returns a tidy one: every cell is trimmed of stray spaces, fully empty rows are swept out and exact duplicate rows are removed. It is the fastest way to clean up an export before importing it somewhere else.

After you drop a file in, an inspection report shows what cleaning will do — how many data rows there are, how many are empty or duplicated, and how many cells need trimming — with the problem rows highlighted in a preview. A verdict line tells you exactly how many rows will survive.

You choose the output format (CSV or Excel) and whether the first row is a header; headers are kept as-is and never counted as duplicates. The file is uploaded for processing and cleaned up automatically afterwards, and the result page reports rows kept, empties swept, duplicates removed and cells trimmed.

How to use Spreadsheet Cleaner

1. Drop your spreadsheet onto the page — CSV, XLSX, XLS or TXT up to the size limit.
2. Review the inspection report: empty rows, duplicates and cells with stray spaces are highlighted.
3. Choose the download format (CSV or Excel) and tell the tool whether the first row is a header.
4. Click “Clean it up” and wait while the file is scrubbed.
5. Download the cleaned file and check the summary of what was fixed.
