Instructions

Software Usage Instructions

Import CSV data: Select one or more CSV or TXT files, or switch to text mode and paste CSV content. The batch file interface only shows the first 20 files, but all files will be processed during conversion.
Check the parsing preview: Go to “Conversion Settings” to view the row count, column count, delimiter, and data preview, and confirm that fields are not misaligned.
Configure reading options: You can set the file encoding, input delimiter, text qualifier, and output line ending. If unsure, use auto-detection.
Configure field processing: You can choose to trim spaces before and after fields, skip empty lines, remove BOM, output UTF-8 BOM, and set how tabs and line breaks within fields are handled.
Start conversion: Click “Start Conversion” and the tool will parse the CSV fields and reorganize them into TSV format using tabs.
Download results: A single result can be copied or downloaded as TSV; multiple files can be downloaded as a ZIP package. Files with duplicate names will automatically have numbers appended to their file names for distinction.
Save settings: For frequently used encodings, delimiters, cleanup rules, and file name suffixes, click “Save Settings” to restore them automatically next time.

FAQ

A: CSV usually uses commas to separate fields, while TSV uses tabs. TSV is better suited for scenarios where table data needs to be exchanged in plain text.

A: CSV fields may contain commas, such as in addresses, notes, product names, and other content. The tool recognizes fields wrapped in quotes to avoid mistakenly treating commas inside fields as delimiters.

A: In CSV, two consecutive double quotes are commonly used to represent one double quote within a field. The tool parses according to CSV rules, and you can choose to remove structural quotes, preserve original quotes, or quote all fields.

A: TSV uses tabs as field boundaries. If a field also contains tabs, it may cause columns to be misaligned. It is recommended to replace them with spaces or escape them as \t.

A: Conversion results use the original filename by default and change the extension to .tsv; if duplicate names occur, numeric suffixes such as (2) and (3) are automatically added to distinguish them.

A: You can try UTF-8, GBK, Big5, Shift-JIS, or Windows-1252 in “File Encoding.” To make it easier for Excel to recognize Chinese, you can check Output UTF-8 BOM.
