CSV Quotes Changer

World's Simplest CSV Tool

Free online CSV quote character changer. Just upload your CSV file in the form below and this tool will automatically convert the quote marks to other quote symbols (such as single quotes to double quotes). In the tool options, you can specify the original quotes that are used (that you want to replace) and the new quotes (that you want to use now). You can also customize the field delimiter to match the input file (such as a semicolon-separated file). Created by programmers from team Browserling.

What Is a CSV Quotes Changer?

This tool changes the quotes in CSV (Comma Separated Values) files. Double quotes ("…") in CSV are used to indicate that the data inside them forms a single field. This is particularly important when the data contains commas, newlines, or other special characters that might otherwise be mistaken for delimiters. Thus, by quoting a field, the data inside a field will be always interpreted as a single field, regardless of its content. This tool is super helpful if you're working with a CSV file that uses quotes different from what the target software expects. For example, if your CSV file uses single quotes instead of double quotes, then you can convert the single quotes to double quotes. In the tool options, you can specify the original quote characters, as well as specify the new desired quotes and get a CSV with changed quotes. If needed, you can enclose all CSV values in new quotes, ensuring consistent formatting for all fields in the file. While commas (",") are the most common CSV delimiter, some files may use tabs ("\t") or semicolons (";"). To adapt to your CSV file format, you can specify its field delimiter character in the options. In addition to changing quotes, the program can also clean your CSV file from unnecessary information. Specifically, it can remove empty lines and comments (which start with the specified comment character that you can adjust in the options). Csv-abulous!


CSV Quotes Changer Examples

Convert Double Quotes to Single Quotes

In this example, we convert a CSV file about fish and their lifespans with the standard double quotes (") to single quotes ('). The double quotes in this file are used to capture multi-word values (such as "Fish Type") as individual CSV fields and represent them as a single value. By changing the double quotes to single quotes, we adapt to the requirements of the software that we're using that requires imported files to have single quotes.

"Fish Type","Lifespan" "Clownfish","10 to 30" "Goldfish","10 to 20" "Tuna","15 to 40" "Shark","20 to 70+" "Salmon","5 to 13" "Catfish","20 to 50"
'Fish Type','Lifespan' 'Clownfish','10 to 30' 'Goldfish','10 to 20' 'Tuna','15 to 40' 'Shark','20 to 70+' 'Salmon','5 to 13' 'Catfish','20 to 50'

Get rid of comment lines in the

Change Quotes in Numeric CSV Data

In this example, we upload a CSV file containing monthly statistics of active users for various social media platforms. The original CSV file uses double quotes (") to wrap fields with large numbers, where the comma serves as a delimiter for digit groups within the number (such as "400,000,000"). As these commas are not field delimiters, each such number must be enclosed in quotes. By changing double quotes around numbers to single quotes, we deactivate the "Quote All Fields" mode so that the program only places new single quotes around numeric fields where they are actually necessary.

Platform,Monthly Active Users Facebook,"3,000,000,000" YouTube,"2,400,000,000" WhatsApp,"2,000,000,000" WeChat,"1,300,000,000" Instagram,"1,200,000,000" TikTok,"1,000,000,000" Telegram,"700,000,000" Snapchat,"500,000,000" Pinterest,"400,000,000" Twitter,"400,000,000"

Restore Regular Double Quotes in a CSV File

In this example, we import CSV data about various cheeses that have been extracted from an older database. Instead of a regular comma, this database uses a semicolon as a delimiter, and instead of regular double quotes, it uses single quotes. To make this file work in newer databases that expect standard CSV, we specify the semicolon symbol (;) in the input delimiter field and set the input quotation symbol as a single quote ('). As a result, we change all single quotes to double quotes, all semicolons to commas, and also clean the file from empty lines and comments starting with the "#" symbol.

'cheese';'texture';'aging_time' 'Cheddar';'Hard';'3–24 months' 'Parmesan';'Hard';'12–36 months' 'Brie';'Soft';'5–6 weeks' 'Feta';'Soft';'3–4 months' 'Gorgonzola';'Soft';'3–4 months' #'Mozzarella'
