Output is tab-separated — ideal for pasting directly into a spreadsheet.
Convert CSV into tab-delimited text
Tab-delimited text is one of the most reliable interchange formats because the tab character almost never appears inside real data. To convert CSV to tab delimited text file, this tool swaps the commas for tabs while keeping every column intact.
Paste or upload your CSV and download a TSV file, or copy the text and paste it directly into Excel or Google Sheets, where tab-separated content drops neatly into columns. Quoting is applied only if a value still needs it.
Want a different target? See comma, pipe or fixed-width output, or the general delimited text tool.
How to use it

TSVは値の中にカンマが含まれるという典型的な問題を回避します。
Tabs rarely collide with data
Names, notes and addresses often contain commas, which forces quoting in CSV. Tabs almost never appear inside such values, so tab-separated text usually needs no quoting at all and is easy for other tools to read.
Paste straight into Excel
Copy the output and paste it into a spreadsheet: tab-separated text is split into columns automatically, without the import dialog. This makes TSV a fast bridge between systems and Excel.
When a value contains a tab
In the rare case a field already contains a tab or line break, it is quoted so the column boundaries stay correct.
Line endings and encoding
Choose CRLF for Windows or LF for Unix, and enable UTF-8 BOM if the file will be opened in Excel with non-Latin text.
Tab-separated text and spreadsheets
Tab-separated values occupy a sweet spot between human readability and machine safety. Because a tab is whitespace, the file looks tidy in an editor, yet because tabs are rare inside ordinary data, the format usually avoids the quoting gymnastics that comma files require. The most useful property in day-to-day work is how spreadsheets treat it: copy tab-separated text and paste it into Excel or Google Sheets and the columns simply appear, with no import wizard and no delimiter prompt. That makes TSV an excellent bridge when you are moving data out of one system and into a spreadsheet by hand. For files saved to disk, choose CRLF endings if a Windows tool will read them, keep UTF-8 for international text, and add the BOM only when Excel is the target. Should any value contain a tab or newline, it is quoted so the structure holds.
