How CSV Delimiter Converter works

  1. Paste your comma-separated data into the Input box.
  2. Type your target delimiter into Option A: 'tab', 'semicolon', or 'pipe' (tab is used by default).
  3. The Output panel updates instantly with each row rejoined using your chosen delimiter.
  4. Click Copy, then paste the result into your spreadsheet, database import tool, or legacy system.
  • Convert a comma-separated export to tab-delimited (TSV) for pasting directly into spreadsheet cells as separate columns.
  • Produce semicolon-delimited CSV for European Excel locales that treat commas as decimal separators.
  • Reformat data for an older import tool or legacy system that only accepts pipe-delimited files.
  • Prepare data for a database bulk-load utility that expects a specific field separator.

Your data is reformatted entirely in your browser's memory — nothing is uploaded or sent to a server.

  • The parser splits on every comma in the input and does not respect quoted fields, so commas embedded inside a quoted value will be split into extra columns incorrectly.
  • Only comma-separated input is accepted — it doesn't auto-detect or convert from other source delimiters.
  • Only three target delimiters are supported (tab, semicolon, pipe); custom or multi-character delimiters aren't available.

CSV Delimiter Converter

CSV Delimiter Converter changes comma-separated rows into tab, semicolon, or pipe-delimited output. It helps when moving data between spreadsheets, databases, and older import tools.

FAQ

Frequently asked questions

Is CSV Delimiter Converter free to use?

Yes. The tool is free and runs directly in your browser with no account required.

Does this tool upload my data?

No. Processing happens locally in the browser tab. Your input is not sent to a server.

What is this tool best for?

Converting comma-separated data to the delimiter an older import tool, European spreadsheet locale, or legacy database loader expects.

Which output delimiters are supported?

Tab (TSV), semicolon, and pipe (|). Tab is the default if Option A is left blank or set to anything other than 'semicolon' or 'pipe'.

Why would I need semicolon-delimited output?

Many European locales configure Excel to use a comma as the decimal separator, so Excel expects semicolons between CSV fields instead of commas to avoid ambiguity.

Does it convert from formats other than comma-separated?

No — the input must be comma-separated. This tool only changes the output delimiter, not the input format.

Does it handle quoted fields with commas inside them?

No. The parser splits every line on commas and strips a leading/trailing quote character only, so a quoted field containing a comma will be split into extra columns incorrectly.

Can I convert to TSV for pasting into Excel or Google Sheets?

Yes — tab-delimited output pastes directly into spreadsheet cells as separate columns, which is one of the most common uses for this converter.
