Remove carriage returns (\r) and newlines (\n) embedded inside cells

When users enter comments, delivery instructions, or notes in multi-line text boxes, carriage returns (\r) and line feeds (\n) get saved inside the database field. While the RFC 4180 CSV specification allows multiline cells as long as the entire field is wrapped in double quotes, in practice multiline cells cause endless headaches: - Many command-line Unix tools (awk, grep, cut) and simple CSV parsers split rows strictly on newline characters, causing multiline cells to fragment single records across multiple broken lines. - Database bulk load utilities (PostgreSQL COPY, MySQL LOAD DATA INFILE) can fail or miscount rows. - Viewing datasets in terminal pagers or text editors becomes messy and difficult to read. This tool scans your spreadsheet, parses multiline cells cleanly, and replaces embedded newlines (\r\n, \r, \n) with your choice of replacement character: - A clean single space ("Line 1. Line 2.") - A semicolon separator ("Line 1; Line 2") - A custom delimiter string All processing executes locally in your browser sandbox via Web Workers. Your private customer comments and internal notes are never uploaded to any remote server. From an ETL pipeline and database loading standpoint, embedded carriage returns ( ) and newlines ( ) inside spreadsheet cells cause standard Unix tools (awk, grep) and database bulk loaders to fragment single records across multiple broken lines. DataFix parses multiline cells cleanly, replacing internal line breaks with spaces or semicolons, ensuring that every record occupies exactly one physical line. From an enterprise governance perspective, customer feedback records, internal incident logs, and employee notes contain confidential information. Uploading datasets to public web formatters violates internal security guidelines. DataFix processes all line break removal locally within your browser sandbox via Web Workers, ensuring that your data remains strictly confidential and secure. In data warehousing and automated database loading (PostgreSQL COPY, MySQL LOAD DATA), multi-line text entries represent a frequent source of pipeline failures. When customer reviews or notes contain embedded line breaks, standard text loaders interpret the break as the start of a new record, causing column misalignments and type mismatch errors. Replacing internal line breaks with clean spaces or semicolons ensures that each record occupies exactly one physical line, ensuring smooth bulk loading.

Will this make every row fit on exactly one line?

Yes! Removing internal newlines ensures every CSV record occupies exactly one physical line.

Can I replace newlines with a semicolon instead of a space?

Yes. Select the "Replace with semicolon" chip to separate multi-line notes with "; ".

Does this handle both Windows (CRLF) and Unix (LF) line breaks?

Yes. It recognizes and normalizes \r\n, \r, and \n.

Is my data private?

Completely. All data processing occurs locally within your browser sandbox via Web Workers.
