Frequently asked questions
- Why does my CSV open as one long column in Excel?
- Excel splits on the separator of your system locale — a semicolon in much of Europe, a comma elsewhere. A comma-separated file opened in a semicolon locale lands in a single column. Viewing it here shows the real structure regardless of locale.
- How are commas inside a field handled?
- A field containing the separator is wrapped in double quotes, and a quote inside it is doubled. Both are parsed correctly here, which is where hand-written split-on-comma code usually falls over.
- Can I convert a CSV to JSON or a Markdown table?
- Yes — both, using the header row as the keys or the column titles. Useful for dropping a spreadsheet extract straight into a README or a config file.
- Why do my accented characters look wrong?
- The file was almost certainly saved in a legacy encoding rather than UTF-8. Re-exporting as UTF-8 from the source application is the fix — the alternative is guessing at a code page and getting it wrong on a different row.
