Frequently Asked Questions
The validator checks for: CSV parse errors, inconsistent column counts across rows, empty cells, and overall file structure. It provides a detailed report with row numbers for any issues found.
Inconsistent column counts are reported as warnings, not errors. While a well-formed CSV should have the same number of columns in each row, the file may still be processable. The validator shows you which rows have mismatched column counts.
Empty cells are identified and reported with their row and column numbers. The first 5 empty cells are listed individually, and if there are more, a summary count is provided. Empty cells are warnings, not errors.
Yes, you can specify the delimiter used in your CSV file (comma, semicolon, tab, pipe, etc.) or use "auto" detection. The validator will use the specified delimiter when parsing and checking the file structure.
