Quick Answer

Paste columns of text and get CSV. Each line becomes a row, and the tool splits a line wherever it finds a tab or a run of two or more spaces. Single spaces inside a value are kept. Any field containing a comma or a quote is wrapped in double quotes. It all runs in your browser, with nothing uploaded.

What the Text to CSV Converter Does

This converts plain, column-aligned text into CSV. Wherever a line has a tab or two or more spaces, the tool treats that as a column break; a single space is left inside the value. Each line of text becomes one CSV row.

Fields that contain a comma or a double quote are wrapped in double quotes so they survive as a single CSV field. The result is ready to copy or download as a .csv file.

How It Works

Paste or type your text. Blank space around the whole block is trimmed first.

Each line is split into fields wherever a tab or a run of two or more spaces appears, then the fields are joined with commas.

A field containing a comma or a quote is wrapped in double quotes. Copy the CSV or download it — all in your browser.

Data source & conversion logic

  1. Trim and split lines. The whole block is trimmed, then divided into lines.
  2. Detect column breaks. Each line is split on a tab or a run of two or more spaces.
  3. Join with commas. Fields are joined with commas; one with a comma or quote is wrapped in double quotes.
  4. Output the CSV. The rows are ready to copy or download as a .csv file.

How text becomes CSV

Each line = one CSV row Split each line on a tab or a run of 2+ spaces Join the fields with commas A field with a comma or quote is wrapped in double quotes
Worked example
Two columns separated by several spaces, name then age, become name,age. A value like Paris, France keeps its comma and is wrapped as "Paris, France".

A single space does not split a column, so multi-word values stay intact. Internal double quotes are wrapped but not doubled — see the limitations.

Privacy

Your text is processed entirely in your browser — there is no server and nothing is uploaded.

The data never leaves your device, so even sensitive records stay private.

No account, no stored copy; the conversion is gone when you close the tab.

Standards & references

  • RFC 4180 (CSV) — The common CSV format: fields with a comma, quote or line break should be quoted, with internal quotes doubled.
  • Delimiter handling — This tool treats a tab or a run of two or more spaces as the column delimiter; a single space stays inside the value.

Accuracy & Limitations

Columns are detected by a tab or a run of two or more spaces. If your data uses single spaces between columns, they will not split — separate columns with a tab or at least two spaces.

A single space inside a value is preserved, so multi-word values such as a full name stay in one field.

Quoting is simplified. A field with a comma or quote is wrapped in double quotes, but an internal double quote is not doubled. Under RFC 4180 an internal quote should be written twice, so a value that already contains a quote may not be perfectly escaped — check those fields.

Empty lines become empty rows, and the block is trimmed first, so leading and trailing blank lines are removed.

Real-World Use Cases

Convert a pasted table

Turn columns copied from a document or terminal into a CSV file.

Spreadsheet paste

Convert tab-separated text copied from a spreadsheet into CSV.

Clean up aligned text

Make CSV from space-aligned columns in a log or report.

Quick import file

Produce a simple CSV to import into another tool.

When to use it — and when not to

Good for

  • Tab-separated or space-aligned columns
  • Quickly turning pasted text into CSV
  • Data without awkward embedded quotes

Not the best choice for

  • Columns separated by single spaces only
  • Values that contain embedded double quotes
  • Fields that themselves contain tabs

If your text is strictly tab-separated, the TSV to CSV converter handles quoting more strictly. For values with embedded quotes, fix the escaping in a spreadsheet.

Frequently Asked Questions

How does it decide where columns are?
It splits each line wherever there is a tab or a run of two or more spaces. Those mark the column breaks.
Do single spaces split a column?
No. A single space stays inside the value, so multi-word values such as a full name remain in one field.
What about a field with a comma?
It is wrapped in double quotes so the comma does not look like a column break, keeping it as one CSV field.
Does it escape internal quotes?
It wraps a quote-bearing field in double quotes but does not double the internal quote. That is not fully RFC 4180, so check any value that already contains a double quote.
Can I use a tab as the separator?
Yes. A tab is treated as a column break, the same as a run of two or more spaces.
What if my columns use single spaces?
They will not split. Re-separate the columns with a tab or at least two spaces first.
Are blank lines kept?
Leading and trailing blank lines are trimmed away; a blank line in the middle becomes an empty row.
What format do I get?
A CSV (.csv) you can copy or download.
Is this RFC 4180 compliant?
Mostly. It quotes comma- and quote-bearing fields, but it does not double an internal quote, which is the one gap.
Can it read a real TSV file?
For strictly tab-separated data, the TSV to CSV converter is a better fit and quotes more strictly.
Is my data uploaded?
No. The conversion runs entirely in your browser, so nothing leaves your device.
How do I view the CSV as a table?
Use the CSV viewer, or the CSV to JSON converter to work with it as data.

References

Splits each line of your text on a tab or a run of two-or-more spaces and joins the fields with commas, wrapping any field that contains a comma or quote. Runs entirely in your browser. Note: it wraps but does not double an internal quote, so check fields that already contain double quotes.
