Frequently asked questions

Does it detect numbers and booleans?: Yes, cells that look like integers, decimals, or "true"/"false" are converted to the matching YAML type instead of staying as quoted strings.
Can I use a different delimiter?: Yes, choose comma, semicolon or tab from the delimiter selector.
Are empty rows included?: No, fully blank rows are skipped automatically.
