Data Cleanup tips

🧹

Paste raw data exports with inconsistent whitespace. Enable "Trim whitespace" and "Remove duplicates" to produce a clean, unique set of values.

💡

Log files often contain repeated identical lines. Sort + deduplicate to get a unique list of error messages or events for analysis.

📊

Excel/Sheets exports sometimes have trailing spaces that break lookups. Trim whitespace here before re-importing for reliable data joins.

🔧

Remove empty lines to compact your data. The option strips any blank lines — including lines that are only whitespace after trimming.
