Spreadsheet cleanup is often less about making a sheet look neat and more about making the data dependable. Duplicate records, stray spaces, invisible characters, blank rows, inconsistent capitalization, and mixed value formats can break lookups, inflate counts, and create false differences between files. The cleanup tools in this section are aimed at those everyday problems that accumulate after copy-and-paste work, exports from older systems, and manual data entry.
The safest cleanup process is selective. Removing every blank, symbol, or duplicate without checking context can damage legitimate records. For example, two customers can share the same name, a blank cell can be meaningful, and spacing may matter in product codes. Start by identifying the column or issue you want to fix, preview a few affected rows, then run the cleanup and compare the result with the original before replacing any working file.
Practical tips
- Clean one type of problem at a time so changes are easy to review.
- Treat duplicate detection as a review step, not an automatic deletion rule.
- Pay extra attention to codes, SKUs, phone numbers, and other text-like numeric fields.
- Normalize spaces and casing before comparing names or categories.
- Re-run counts and key totals after cleanup to catch accidental data loss.
