What kinds of input can these tools parse?

They cover fixed-width records, mixed-delimiter text, key-value lines, Apache or Nginx access logs, logfmt, and tables embedded in Markdown or HTML.

How should I handle fixed-width or mixed-delimiter data?

Start by detecting explicit column boundaries or delimiters, then use a pipeline to normalize whitespace, remove noise, and inspect the resulting records before exporting them.

Which tools help with application and web logs?

Use the access-log parser for Apache or Nginx lines, the logfmt bridge for key-value logs, and the structured-log analyzer when the format or field types need to be inferred.

Should I clean text before parsing it?

Usually yes. Trim and normalize the source first, but keep the pipeline output and anomaly report so you can review what changed before loading the records downstream.
