Why people use BulkConverter

Convert thousands of coordinates in seconds (CSV → CSV).
Quickly validate a single point before bulk conversion.
Simple UI — explicit From/To CRS (no hidden defaults).

Tips

Created your CSV from Excel? Make sure your coordinates use a dot as decimal separator (e.g. 52.123) — not a comma (52,123).
If your decimals use commas, your CSV delimiter is often a semicolon (;).
Not sure which CRS you have? Try a single conversion first — if the map jumps to the wrong continent, your CRS (or X/Y order) is likely wrong.
