Frequently Asked Questions

What sort of text files can I convert?
This tool works best with structured data, like logs from a Sydney data centre, fixed-width government reports, or pipe-separated exports from accounting software.
Can it convert unstructured writing like emails?
No. It's designed for structured data, not prose. You must define the structure (like delimiters) so the output is accurate.
When should I pick fixed-width mode?
Use this when data columns align by specific character counts, common in older mainframe outputs or legacy system reports.
How do I add column headers?
Type your column names separated by commas in the 'Optional header row' field, and they will be applied to the top of your data.
Is my data safe?
Absolutely. The conversion runs locally in your browser, so your sensitive text never touches our servers.

Expert Tips

  • If your source text uses tabs, copy the actual tab character into the delimiter field rather than typing the word 'tab'.
  • For fixed-width conversions, use a monospaced text editor to double-check your character counts before parsing.
  • Utilise the 'Skip lines' feature to ignore report headers or timestamps that appear before your data starts.
  • Manually adding a header row is useful when you import raw data dumps into Excel for analysis.
  • Check the preview pane before you download to ensure columns haven't shifted or merged incorrectly.
