ExisEcho

ExisEcho uses fuzzy logic algorithms to find duplicate and similar records in your Excel data — even when they're

misspelled, abbreviated, or formatted differently. Catch the duplicates that VLOOKUP and exact-match filters miss.

Features

• Fuzzy Matching — Detects near-matches like "Jonh Smith" vs "John Smith" or "123 Main St" vs "123 Main

  Street"

• Misspelling in Data — Detects misspelled duplicates in any data"
• Phonetic Matching — Finds names that sound alike (e.g., "Steven" vs "Stephen")
• Synonym Detection — Equates nicknames and abbreviations (Bob = Robert, St = Street)
• Configurable Options — Fine-tune matching per column: ignore case, word order, punctuation, honorifics, and

  more

• Adjustable Threshold — Slide from loose to strict matching to control sensitivity
• Color-Coded Results — Duplicate groups are highlighted in your spreadsheet for easy review

  sheet
