What Is a CSV Column Sorter?

This tool sorts columns of Comma-Separated Values (CSV) files. The program sorts data based on the selected column similar to the sort function in Excel or Google Sheets. Once you specify a column to sort, it rearranges all CSV rows so that the values in the chosen column are sorted. The column that needs to be sorted can be specified in two ways: using its position (number) or header value (name). Column numbering starts from 1 and then goes 2, 3, and so on. You can also use reverse numbering (numbering from the last column), which starts from -1 and then goes -2, -3, and so on. If there are multiple fields with identical values in the selected column, the program uses a stable sort algorithm and outputs these rows in their original order. However, you can activate secondary sorting in this case. In the "Secondary Sort Columns" option, you can enter positions of alternative columns to sort by in case of identical values in the primary column. For example, if you initially sort the CSV by column 1 and there are identical values, you can enter the following columns in the secondary sort option: "2, 3". This means: in case of identical values in the 1st column, sort by the 2nd column, and in case of identical values in the 2nd column, sort again by the 3rd. You can specify any number of secondary columns and they can be in any order. The same sorting rules can be applied to the header-based mode. For example, you can first sort the CSV by a column with the header name "city" and then input secondary sort columns with headers "street" and "postcode" (one per line). When a CSV is sorted, the CSV headers can be fixed at the top and not moved or sorted along with other values. Use the "Sort Headers" option to configure this behavior. The tool offers several sorting methods. The first method is alphabetical sorting. In this mode, the tool rearranges all column values in the order defined in the ASCII and Unicode tables. The second method is numerical sorting. In this mode, the tool sorts numbers from the smallest to the largest or vice versa. This mode supports big number arithmetic and can sort arbitrarily large values. The third method is sorting by length. In this mode, the tool arranges values from the shortest to the longest or vice versa. The fourth method is sorting by complexity. In this mode, the tool calculates entropy (unpredictability of characters) and arranges values from the easiest to the most complex or vice versa. As mentioned, the sorting order can be ascending or descending, and it can be adjusted in the options. Additionally, you can choose in the options whether sorting should be case-sensitive or not. Besides just sorting, the utility can also fix a corrupted CSV file. Specifically, if some fields are missing in the CSV file, you can leave them as they are or replace them with empty values or custom strings. Additionally, if the CSV contains comments, you can specify in the options which symbol starts comments (e.g., "#" or "//"), and if necessary, remove them. Furthermore, you can delete all empty lines from the CSV file to tidy it up. Csv-abulous!

CSV Column Sorter Examples

Sort CSV Alphabetically by the First Column

In this example, we sort CSV data alphabetically by the first column. The CSV consists of two columns, where the first column contains letters of the alphabet, and the second column represents the position of each letter in the alphabet. We specify the sort column by its position as "1" and sort it alphabetically in increasing order.

f,6 b,2 a,1 c,3 d,4 e,5
a,1 b,2 c,3 d,4 e,5 f,6
Required options
These options will be used automatically if you select this example.

Sort Chemical Elements by Proton Count

In this example, we sort CSV data with chemical elements by the "protonNum" (proton number or proton count) column. We specify the name of this column in the options and choose the mode that sorts a CSV by the header. We also switch to the numerical sorting algorithm and output the CSV data sorted from the smallest proton number to the largest.

symbol,protonNum B,5 Be,4 C,6 F,9 H,1 He,2 Li,3 N,7 O,8
symbol,protonNum H,1 He,2 Li,3 Be,4 B,5 C,6 N,7 O,8 F,9

Multi-column Sorting of CSV by Length

In this example, we're working with a CSV file containing playing card suits and we sort it by length across multiple columns. First, we sort the data by the 1st column in decreasing order, moving values with the highest number of "♠" to the top. Then, we sort the data by the 2nd column, moving values with the highest number of "♣" to the top. Finally, we sort the data by the 3rd column, moving values with the highest number of "♥" to the top.

♠♠♠,♣♣,♥♥,♦ ♠♠♠♠,♣♣♣,♥♥,♦ ♠♠♠,♣♣,♥,♦ ♠♠♠,♣♣♣,♥♥,♦
♠♠♠♠,♣♣♣,♥♥,♦ ♠♠♠,♣♣♣,♥♥,♦ ♠♠♠,♣♣,♥♥,♦ ♠♠♠,♣♣,♥,♦

Sort a CSV by Two Columns

In this example, we sort CSV columns alphabetically in ascending order by the "leap" column. We specify this column in the options via its header name and add a secondary sort by the "year" column. As a result, the program puts all non-leap years at the top and then sorts the years from smallest to largest. We also activate the CSV cleaning options to remove comments starting with the "#" symbol and empty lines.

year,leap,start 2088,true,Fri 2035,false,Mon 2064,true,Wed 2040,false,Mon 2072,true,Sat #2033 2032,true,Thu 2080,false,Tue 2048,true,Fri

We specify the column containing passwords for sorting by its position "2". Additionally, we replace incomplete data (missing passwords) with a custom string "***".

login,password kitty,12345 doggo,ilovebones pizza gamer,contrOLler dream,dr%e$am!1
login,password dream,dr%e$am!1 gamer,contrOLler doggo,ilovebones kitty,12345 pizza,***
