What it does

BulkPro Excel Cleaner turns messy data in Excel and CSV files into usable data. It removes duplicate rows, strips empty rows and columns, collapses extra spaces, normalizes Turkish characters to ASCII and fills empty cells. It is ideal for a fast, bulk cleanup before merging CRM data, reporting, or sending data to analysis.

How to use it

  1. 1Drag the Excel/CSV files onto the list.
  2. 2Optionally pick a Worksheet and the columns to clean (blank = all text columns).
  3. 3Tick the cleaning operations to apply.
  4. 4Hit Run. A cleaned copy of each file is produced.

Use cases

Standardize a CRM list

Remove duplicate rows + trim whitespace + fill empty cells with N/A. A spotless customer list.

ASCII before a legacy import

Turkish -> ASCII turns sahin into sahin so legacy systems that reject non-ASCII accept the data cleanly.

Clean a single column

Pick a Worksheet and one column (e.g. email), uppercase + trim spaces. Other columns are untouched.
