Convert CSV line endings to Windows CRLF, Unix LF, or classic CR locally while preserving the file's row content. The original file stays unchanged.
This line ending converter examines the selected output choice: XLSX means CRLF, CSV means LF, TSV means CR, and JSON means auto-normalized LF. It performs the work locally and leaves the source file untouched.
Keep the source file and review the output before using it in a production workflow.
The tool accepts XLSX, XLS, CSV, and TSV. It reads cell data in the browser; macros, charts, external links, and advanced Excel formatting are outside its preservation scope.
| Format | Support |
|---|---|
| XLSX / XLS | Cell data and workbook structure where applicable |
| CSV / TSV | Delimited text parsed locally |
No. The line ending converter reads and processes the selected file inside your browser. Your spreadsheet is not sent to Calloffice.
XLSX, XLS, CSV, and TSV files are accepted. Older or unusually structured workbooks may lose unsupported Excel-only features in a generated output.
Blank cells remain distinguishable from zero and text. The exact treatment is shown in the preview and described in the downloaded result.
The tool focuses on cell data and its stated task. Formula text is read where relevant, but Excel calculation behavior, charts, macros, and advanced formatting are not guaranteed.
Review the bounded preview and open the downloaded file in a spreadsheet editor. Keep the original workbook until column names, dates, and special values have been verified.
