Sort CSV rows by a column
A long CSV export can be difficult to review when related records are scattered throughout the file. Sorting brings names, dates, categories, or measurements together so you can scan the rows in a useful order. This CSV sorter keeps the first row as the column headings, reorders the data rows by the field you select, and produces a separate CSV result for copying or downloading.
Text order and numeric order
Choose a column, then sort ascending or descending. Text sorting compares values without treating uppercase and lowercase as different and uses natural number ordering for text such as item 2 and item 10. For a column of numbers, switch on numeric comparison: 2 then comes before 10 by numeric value instead of by the first character.
Numeric comparison does not change the values in your file. When both values being compared are numbers, they are ordered numerically; comparisons involving non-numeric text fall back to text order. This is useful for mixed columns, but if a column should be entirely numeric, check for stray labels or symbols that may be stored with the numbers.
Headers, ties, and empty cells
The first row stays fixed as the header; it is never moved into the data rows. When two records have the same sort value, their original order is kept. Empty cells sort as empty text, so they appear near the top in ascending order and near the bottom in descending order. All the other values in each record travel with that row.
For example, sorting these scores numerically in ascending order:
Name,Score
Ravi,12
Ava,3
Liam,20
places Ava first, followed by Ravi and Liam. The names remain paired with their original scores.
Accepted files and the sorted CSV
Upload or paste comma-, semicolon-, tab-, or pipe-separated data. The tool detects the common delimiter and supports quoted fields, including cells with separators, quotation marks, or line breaks. The generated download is comma-separated CSV. Values that need CSV quoting are wrapped in double quotes, and quotes inside a value are doubled.
How to sort a CSV file
- Upload a
.csv,.tsv, or.txtfile, or paste delimited rows. - Select the column whose values should determine the row order.
- Choose ascending or descending, and turn on numeric comparison when appropriate.
- Select Sort rows, review the complete result table, then copy or download the new CSV.
Sorting changes row order only. It does not edit cell values, remove duplicate records, or interpret dates. Dates are compared as text; a consistent format such as YYYY-MM-DD sorts chronologically as text. The source file remains unchanged. Files up to 50 MB are processed in your browser and are not uploaded to RomitCSV.
Frequently asked questions
Does the CSV sorter keep my header row at the top?
Yes. The first row is treated as the headings and stays in place while the remaining rows are sorted.
Why does text sort show item 2 before item 10?
Text sorting uses natural order for number-like parts of a value, which is easier to scan than comparing each character from left to right.
When should I enable numeric comparison?
Use it for values such as counts, scores, or prices when you want 2 to come before 10 numerically. Values stay unchanged in the result.
What happens to rows with matching sort values?
Their initial order is preserved. Sorting one column does not scramble records that tie on that value.
Can I sort dates chronologically?
The sorter compares date strings as text rather than parsing date formats. A consistent year-month-day format generally sorts in calendar order.
Can I sort a semicolon- or tab-delimited file?
Yes. The tool detects common comma, semicolon, tab, and pipe separators. It writes the sorted download as comma-separated CSV.
Does sorting overwrite my source file?
No. The sorted result is separate and can be copied or downloaded as a new file.
Is my data uploaded?
No. The file is read and sorted in your browser.
