Pandas version checks
-
[X] I have checked that this issue has not already been reported.
-
[X] I have confirmed this bug exists on the latest version of pandas.
-
[ ] I have confirmed this bug exists on the main branch of pandas.
Reproducible Example
import pandas as pd
from io import StringIO
csv = 'col1,col2\n""malformed","quotes"",'
io = StringIO(csv)
pd.read_csv(io, on_bad_lines="skip") # or alternatively "warn"
# ParserError: Error tokenizing data. C error: EOF inside string starting at row 1
Issue Description
The combination of
- malformed text with quotes and a delimiter hidden in between
- doublequote=True
- on_bad_lines="skip"
raises a ParserError instead of skipping the malformed row.
Expected Behavior
The reader skips the malformed row and reads the csv successfully.
