About this tool
Prepare usable spreadsheet data
Import up to 20 CSV or TSV files, 10 MB each. Quoted cells and tab separators are supported; XLSX files are not.
Columns are matched by identical header names. Choose whether to trim spaces and remove duplicates or blank rows. Rows with an incorrect number of columns are skipped and counted. Download the cleaned data as CSV or TSV.
