Fix CSV-to-SQLite Conversion Errors

What the error actually means

A CSV-to-SQLite conversion needs valid table and column names plus a consistent record shape. Mixed field values can be preserved as text, but duplicate headers and malformed rows create ambiguous or shifted columns.

Likely causes

  • Headers are blank, duplicated or unsuitable as stable column names.
  • Some rows have a different field count.
  • Quoted delimiters were parsed incorrectly.
  • An inferred type conflicts with later values.

Unambiguous table structure

Problem

id,status,status with a short data row

Correct pattern

id,order_status,payment_status with equal-width rows

A safe repair workflow

  1. 1Run the CSV diagnostic and fix mismatched rows.
  2. 2Make every header unique and stable.
  3. 3Decide whether mixed columns should remain text.
  4. 4Convert, then query the first, last and count of rows.

How to verify the result

A file that downloads successfully is not automatically a correct file. Check the result at both the structural and business-data levels:

  • The SQLite table has the expected columns.
  • Row counts match the source.
  • Leading zeros and nulls remain intentional.
  • Representative queries return the correct records.
