Dedupe on the exact columns that define a match — the whole row, or just an email or ID. Case and stray spaces are ignored, so near-identical rows get caught too.
Excel only matches on the columns you tick, treats " Jane " and "jane" as different, and gives you no say in which copy to keep. On a big export that's a recipe for either missing dupes or deleting the wrong rows.
Open your file and choose Clean → Remove duplicates. Pick the key columns that define a duplicate — the whole row, or just email, or first + last name. Gridzu normalizes case and trims spaces before matching, so " Jane Doe" and "jane doe" collapse into one. It's instant even on files with millions of rows.
Need to find the same record sitting in two files instead? Use Bulk Lookup, or compare the two files directly. Working with a giant export? Gridzu also opens large CSV files without slowing down.
Your file is cleaned entirely on your own machine — Gridzu never sends your data to our servers.
