What is TXT to CSV conversion?

TXT to CSV conversion takes a plain text file (.txt) where data is separated by tabs, spaces, pipes, or other characters and transforms it into a standard comma-separated values file (.csv) that follows the RFC 4180 specification. The resulting CSV file opens directly as a structured table in Excel, Google Sheets, LibreOffice Calc, and any database import tool.

Many data exports, log files, and legacy systems output data as .txt files with tab or space delimiters. Converting these to CSV makes the data portable across all modern spreadsheet and database applications without manual reformatting.

Common .txt file formats this tool handles

Tab-Separated Text (.txt / .tsv)

The most common format for exported spreadsheet data, database dumps, and clipboard copies from Excel or Google Sheets. Each column is separated by a tab character.

Space-Separated Text

Common in scientific data, command-line output, and fixed-width log files. Multiple spaces between columns are collapsed into a single delimiter.

Pipe-Delimited Text

Used in EDI (Electronic Data Interchange), HL7 healthcare data, and some legacy mainframe exports. Each field is separated by the | character.

Semicolon-Separated Text

Standard in European locales where commas are used as decimal separators. Common in SAP exports, French/German data systems, and some CRM platforms.

Example: converting a .txt file to CSV

A typical tab-separated .txt file might look like this:

Name	Email	Department
Alice Johnson	[email protected]	Engineering
Bob Smith	[email protected]	Design
Carol White	[email protected]	Marketing

After conversion with tab as the input delimiter, the CSV output is:

Name,Email,Department
Alice Johnson,[email protected],Engineering
Bob Smith,[email protected],Design
Carol White,[email protected],Marketing

If any field contains commas, quotes, or newlines, the converter automatically wraps it in double quotes per the RFC 4180 standard — so the output is always valid CSV.

Frequently Asked Questions

How do I convert a .txt file to CSV?

Drag and drop your .txt file onto the converter, or open it in a text editor, copy the contents, and paste into the input field. Select the delimiter used in your text file (tab, space, comma, or custom), then click "Convert to CSV". Download the result as a .csv file.

What types of .txt files can be converted to CSV?

Any structured text file can be converted: tab-separated (.tsv), space-separated, pipe-delimited, semicolon-separated, or fixed-width text files. The converter auto-detects common delimiters, or you can specify a custom delimiter character.

What is the difference between TXT and CSV?

A .txt file is a generic plain text file with no standard structure. A .csv file follows the RFC 4180 standard: values are separated by commas, fields containing commas or quotes are properly escaped, and each line represents a row. CSV files open directly in Excel and Google Sheets as structured tables.

Can I convert a tab-separated .txt file to CSV?

Yes. Select "Tab" as the input delimiter and the converter will treat each tab character as a column separator. The output CSV uses commas (or your chosen output delimiter) with proper RFC 4180 quoting for fields that contain special characters.

Is my .txt file uploaded to a server?

No. The entire conversion happens in your browser using JavaScript. Your .txt file is read locally and never transmitted to any server. The tool works completely offline once loaded.
