CSV validator
Find inconsistent columns, broken quotes and duplicate headers, with record numbers and fixes.
Result
Add your input, then select Check CSV.
How to use it
Open a CSV or paste its contents. The first record is treated as the header. Choose a delimiter or let the tool detect it, then review errors and warnings.
What to keep in mind
Checks structure, not encoding, schema types or business totals. Quote errors stop parsing; fix them before checking the remaining records.
Up to 2 MB per input, with smaller limits for complex operations. Clear removes the current input and result.
