## Frequently asked questions

### Why keep text parsing, table extraction, and log parsing together?

They share the same delivery problem: irregular text must become records with stable columns, documented assumptions, and an export format that another system can trust.

### When should fixed-width parsing be used?

Use it when columns are defined by character positions rather than delimiters, such as legacy reports, mainframe exports, or copied terminal tables.

### Should malformed CSV rows be repaired before or after conversion?

Repair them after the first structured export exposes row-length problems, but before the data is imported into a spreadsheet, database, or analytics tool.

### Can this workflow infer the perfect schema automatically?

No. It can infer structure and surface anomalies, but column names, data types, required fields, and downstream acceptance rules still need review.
