Identifies structural and encoding issues locally on your Mac before any repairs are planned.

Flags rows containing too few or too many fields compared to the detected table structure.

Delimiter and encoding detection

Detects delimiters (comma, semicolon, tab, pipe) and normalizes UTF-8, UTF-16, and line endings.

Interactive guided repair

Review detected issues with previews. You stay in control of which repairs to apply.

Interactive boundary merge

Click adjacent field boundaries to merge split values caused by unescaped delimiters.

Empty field insertion

Align short rows by selecting the insertion point to restore consistent field count.

Header resolution

Assign column names to unnamed or duplicated headers before saving.

Quoting review

Review flagged quoting anomalies and apply conservative, structurally safe repairs.
