Remove Duplicate Rows from Excel Spreadsheets Locally
Duplicate records in customer email lists, sales rosters, and financial datasets cause skewed analytics, redundant billing, and wasted marketing spend. Manually reviewing thousands of spreadsheet rows to identify duplicates is slow and vulnerable to human oversight.
TabKit Excel Deduplicator hashes and compares rows in local memory. You can deduplicate based on all columns or target specific primary key columns (such as Email or ID), stripping duplicate occurrences while retaining the original record. Your files never touch external servers, safeguarding private customer records.
Frequently Asked Questions
Does deduplication distinguish between uppercase and lowercase text?
You can choose between case-sensitive and case-insensitive comparison, allowing you to treat "[email protected]" and "[email protected]" as duplicates.
Which duplicate row is kept during deduplication?
By default, the first occurrence of a duplicated record is preserved, and subsequent identical entries are pruned from the dataset.
Are my confidential business workbooks uploaded anywhere?
Never. All deduplication logic runs entirely inside client-side JavaScript. Zero bytes leave your web browser.
