CSV 转逗号分隔文本转换器

CSV is already comma-separated, but “convert CSV to comma delimited text file” usually means you want control over the details: which fields are quoted, how line breaks are written, and a predictable text file you can hand to another system.

Paste or upload the CSV and this tool re-emits it as comma-delimited text with the exact quoting rule you choose. The live preview confirms the columns, and you can copy the text or download it as a file.

Need a different separator? See tab, pipe or the general CSV to delimited text tool.

CSV exported as comma-delimited text, with safe quoting where needed.

Quote only when needed

The default wraps a field in quotes only if it contains a comma, a quote or a line break. This produces the most compact, standard comma-delimited text and re-imports correctly everywhere.

Quote every field

Some strict importers expect every value quoted. Choose 全部加引号 and each field is wrapped, which removes any ambiguity about where columns begin and end.

No quotes at all

If you have guaranteed that no value contains a comma, 不加引号 gives the simplest output. Use it carefully — a stray comma would shift columns.

Line endings

Pick CRLF for Windows targets or LF for Unix and most programming tools, so the receiving system reads your line breaks correctly.

Comma-delimited text is the default interchange format precisely because almost every program understands it, from spreadsheets to programming languages to database loaders. The trade-off is that commas are also extremely common inside real data — addresses, descriptions, amounts — which is why quoting exists. When you export here, think about the receiver: a tolerant importer is happy with quote-when-needed output, while a strict, hand-written parser may be safer with every field quoted. If you are sending the file to a colleague who will open it in Excel, keep quoting minimal and add the UTF-8 BOM. If you are feeding an automated pipeline, quote-all removes any guesswork about column boundaries. Either way, comma-delimited text stays the most portable choice, and you can re-import the result with the text-to-CSV tool to confirm it round-trips cleanly before you hand it off. A quick round-trip check like that is the cheapest insurance against a malformed file reaching a production system or a client’s inbox.
