LOCAL CSV CONVERSION
Convert comma-separated data to TSV
Paste CSV or choose a file. Quoted commas, embedded line breaks, escaped quotes, and empty cells are handled in your browser.
UTF-8 CSV up to 10 MB. Comma delimiter only; quoted fields may contain commas and line breaks.
Tabs separate columns. Fields containing tabs, line breaks, or quotes are quoted for safe TSV exchange.
Limitations: this uses comma-separated input and does not detect semicolon or pipe delimiters. Malformed unclosed quotes and non-UTF-8 files are rejected. Rows with different field counts are preserved as-is.
使い方
使い方
- Choose a CSV file or paste CSV text into the input.
- Review the parsed rows and TSV preview.
- Copy the TSV result or download it as a .tsv file.
Quoted CSV fields stay intact
The parser handles commas inside double-quoted fields, line breaks inside quoted fields, and escaped double quotes written as two double quotes. Rows may have different numbers of fields; missing cells are not invented or padded.
TSV output and empty values
Output fields are separated by tab characters. A TSV field is wrapped in double quotes when it contains a tab, line break, or double quote, and embedded quotes are doubled. Empty fields and empty rows are preserved.
Local processing and practical limits
Parsing, previewing, copying, and downloading happen locally in this browser. This tool expects comma-separated input and does not infer semicolon, pipe, or locale-specific delimiters. A UTF-8 BOM is ignored; other encodings, malformed unclosed quotes, and files larger than 10 MB are rejected.
よくある質問
あわせて知りたいこと
Are my CSV files uploaded?
No. The file is read and converted in your browser; it is not sent to a processing server.
Can CSV fields contain commas or new lines?
Yes. Put those fields in double quotes. The converter keeps quoted commas and line breaks as part of the field.
How are tabs and line breaks represented in TSV?
Fields containing a tab, line break, or double quote are double-quoted in the TSV output, with embedded double quotes doubled.
Does it detect semicolon-separated CSV?
No. The parser uses commas as the CSV delimiter. Convert semicolon- or pipe-delimited data first.
