使い方
使い方
- Paste CSV with quoted fields, line breaks, or escaped quotes.
- Choose the separator, header behavior, type detection, and YAML indentation.
- Review the YAML, copy it, or download it as a .yaml file.
CSV parsing that respects real fields
Quoted commas, quoted line breaks, and doubled quotes are parsed according to common CSV rules. Rows must have the same number of fields, and header names must be non-empty and unique.
Safe YAML values
Optional type detection converts true, false, null, and safe numeric values. Empty cells remain empty strings unless you choose type detection, which still keeps blank cells as empty strings.
Local and bounded
Conversion, copying, and downloading run in this browser. Input is limited to 100,000 characters, 10,000 data rows, and 500 columns.
よくある質問
あわせて知りたいこと
Does this upload my CSV?
No. The CSV is parsed and converted locally in your browser.
How are duplicate columns handled?
Duplicate or empty header names produce a clear error so the YAML keys stay unambiguous.
Can I convert CSV without headers?
Yes. Turn off the header option and the tool creates column_1, column_2, and so on.
Are values always strings?
You can keep every cell as text or enable detection for booleans, null, and safe numbers.
