About this category

CSV exports arrive with broken encoding, stray empty columns and duplicate rows — and opening them in Excel can silently turn long numbers into scientific notation or strip the leading zeros off an order ID. These tools parse everything as text without guessing types, so phone numbers, ID numbers and order references stay exactly as they were. Results export to CSV, JSON, a Markdown table or SQL insert statements.

Frequently asked questions

Why does Excel drop the leading zero from my IDs?

Excel auto-detects a numeric type. These tools treat every field as text, so no original character is ever rewritten.

How large a CSV can I process?

Tens of thousands of rows run smoothly. Beyond a hundred thousand, filter columns first to cut the data volume.

Can it fix garbled non-English characters?

Yes. Both UTF-8 and legacy encodings are detected, and you can switch encoding manually and re-parse.
