Free online CSV column appender. Just upload your CSV file in the form below, paste the new column in the options, and it will automatically get added after the last column of your CSV. In the tool options, you can also enter more than one column, as well as filter the input data, and remove comments and empty lines. Created by programmers from team Browserling.
This tool appends an additional column at the end of existing CSV data. It places the new column on the right, preserving the original input CSV columns on the left. You can input the new column (or multiple columns) in the "Columns to Append" section of the tool's options. The new column should have as many records as the original CSV file. If you're adding multiple columns, then they should have the standard comma-separated CSV format. This program also allows you to manage missing data fields if CSV data is incomplete. Specifically, you can choose to ignore missing fields, delete rows with missing fields, fill missing fields with empty values, or fill missing fields with custom values. You can select the preferred mode from the list in the options, and also specify the custom field value to use. Additionally, the utility allows you to clean up the input CSV from unnecessary data rows. In particular, you can remove comment lines by specifying the symbol that starts a comment and get rid of blank lines that don't contain anything. If you want to add a new column in a different position, you can use our Insert CSV Columns tool, and to quickly prepend a column to the beginning of the data, you can use our Prepend CSV Columns tool. Csv-abulous!
In this example, we enhance a CSV dataset containing detailed information about planets and their distances from the Sun (in astronomical units) by adding a new column on the right side. We paste the new "day_length" column in the options, which provides valuable information about the length of day of each planet. The program then appends this new column to the end of the CSV dataset, preserving its original comma-separated structure.
In this example, we load a CSV file containing data about dog breeds and their sizes. After analyzing the file, we realize it lacks two additional data columns – their temperament and life span. Therefore, in the options, we enter two columns with the headers "temperament" and "life_span" and append them to the end of the existing CSV data.
In this example, we add the "playing_time" column to a CSV file containing data about board games. The input CSV already has two columns: "game" and "number_of_players", so the new column becomes the third one. By using the "Clean Up Comment Lines" and "Clean Up Blank Lines" options, we get rid of unnecessary lines and tidy up the input data. Additionally, since the last game in the list lacks a "playing_time" value, we fill the missing value with a custom value "XXmin", which we specify in the options.
You can pass input to this tool via ?input query argument and it will automatically compute output. Here's how to type it in your browser's address bar. Click to try!
