Inspect and clean CSV file encoding in your browser. Remove BOM markers, export as clean UTF-8, and detect encoding hints from the file header. All processing stays on your device.
Detects UTF-8 BOM (0xEF 0xBB 0xBF) and UTF-16 BOM markers. Export with or without BOM depending on what downstream tools require.
Modern browsers can reliably decode UTF-8 and UTF-16 BOM-prefixed files. This tool clearly states what it can and cannot do rather than claiming false support.
