When to change a CSV delimiter
Change the delimiter when a spreadsheet, store, CRM, or database expects a different separator from the one in your source file. This often happens when regional spreadsheet settings export semicolon CSVs.
Quoted values stay intact
The tool parses the file as structured rows before generating the output. Delimiters inside quoted text, escaped quotes, and quoted line breaks are handled as field content rather than new columns or rows.
CSV and TSV output
Choose comma, semicolon, pipe, or tab output. Tab-delimited output downloads with a .tsv extension; other choices download as .csv so the file is easier to identify in later workflows.
Private browser processing
Parsing and conversion happen in the current browser tab. This makes the tool suitable for routine data cleanup without transferring the source file to a processing server.
How to change a CSV delimiter
- Upload a CSV, TSV, or text file, or paste the delimited text.
- Choose comma, semicolon, tab, or pipe as the output delimiter.
- Convert and review the detected delimiter, row count, and data preview.
- Copy the output or download the converted UTF-8 file.
FAQ
What does a CSV delimiter do?
A delimiter separates fields in each row. Commas are common, but spreadsheet exports and regional settings may use semicolons or tabs instead.
Will commas inside quoted values break the conversion?
No. The converter parses quoted fields before writing the new file, so a value such as "Notebook, ruled" remains one field.
Does this upload my CSV file?
No. The current tool reads and converts the file locally in your browser. The file is not sent to UseQuickKit.
Should I use comma or semicolon for Shopify CSV files?
Shopify product CSV files use commas and UTF-8 encoding. Keep the required Shopify column names and structure when preparing an import.
Why add a UTF-8 BOM?
A UTF-8 BOM can help some versions of Excel recognize UTF-8 text correctly. It is added only to the downloaded file when the option is enabled.
Can this repair every malformed CSV file?
No. It can parse standard quoted delimited files, change delimiters, trim values, and remove empty rows. It does not infer missing quotes or rebuild damaged records.
