Delete values that appear more than once. Duplicate values are values that occur more than once in a given set. Read more about duplicate on Wikipedia https://en.wikipedia.org/wiki/Data_deduplication

2 is a duplicate value in [2, 5, 3, 2, 4, 2] because it appears 3 times.

If your data contains duplicated, you can use this tool to clean up your spreadsheet. Having duplicated data will cause future analysis on the dataset to be wrong.

  • Microsoft Excel:
  • Google Sheets: UNIQUE
  • Apple Numbers: UNIQUE
  • Python Pandas: df.drop_duplicates()
  • Related Words: filter unique values, remove duplicates, keep first value

This is normal for a web based application. We recommend uploading data up to 6000 columns and rows. If you encounter lag, you can reduce the sheet size.

There is a fullscreen button on the top right side of the input table. You can also download the table offline to edit with excel which has bigger screen sizes.
