Result

💡 In regex mode, use capture groups in Find like (\d{4})-(\d{2}) and reference them in Replace with $1, $2 — great for reformatting dates, names, or IDs in bulk.

Code tips

💻

Enable case-sensitive matching (leave "case-insensitive" off) so myVar and MyVar stay distinct.

💡

Whole-word matching avoids partial hits when renaming short identifiers like id or x.
