Every cleaning operation you need
Remove Duplicates
Identify and remove identical rows. Works across any column combination — exact or near-duplicate matches caught in one pass.
Trim Whitespace
Strip leading and trailing spaces from every cell. Fixes the invisible formatting that breaks VLOOKUP queries and database imports.
Remove Empty Rows & Columns
Cut blank rows and empty columns that inflate file sizes and confuse downstream tools. Applied selectively or globally.
Fix Casing
Standardize text to UPPERCASE, lowercase, or Title Case per column. Apply to names, company fields, or any text data.
