Remove Empty Rows from a CSV File
CSV exports can include spacer records between sections, empty lines at the end, or rows that contain no values after an export. Those records can make a file harder to scan and may cause trouble when another system expects only usable data rows. This online CSV row remover deletes a data row only when every parsed field is empty or whitespace. You can open a CSV, TSV, or text file, paste delimited data, review the result, and download a separate CSV.
The tool keeps the first row as the header. It also leaves every data row that contains even one value, so removing blank rows will not remove partially completed records.
How the Empty Row Check Works
The tool checks the cells in each data record. Empty cells and cells made only of spaces, tabs, or other whitespace count as blank. A row is removed only when all of its cells meet that condition. The values in rows that remain are not trimmed or otherwise changed.
| Example data row | Result | Why |
|---|---|---|
,, | Removed | All three fields are empty. |
" ", | Removed | The first field contains whitespace only; the second is empty. |
42,, | Kept | The first field contains a value. |
,Pending, | Kept | The second field contains a value. |
| First row | Kept as header | The first row is always preserved and is not checked as a data row. |
This rule is different from filtering on a particular field. If a row has an ID but no email address, it stays because it is not completely empty. To find incomplete records, use the CSV Missing Values Checker.
How to Remove Empty Rows from CSV or TSV
- Select Browse CSV File or drop a CSV, TSV, or plain-text file into the upload area. You can also paste delimited data into the text box.
- Check that the first row contains the headings you want to preserve. The tool always treats the first row as the header.
- Select Remove Empty Rows. The summary shows the data-row and column counts before and after processing.
- Review the cleaned preview, then select Download Cleaned CSV to save the full result.
No settings are needed: the tool uses the same all-cells-empty rule for each data row. You do not need to select columns or change how whitespace is handled.
Headers, Blank Lines, and Delimited Records
The first parsed record is treated as the header. If your source has no header row, its first data record will be preserved as the header and will not be checked for emptiness. Add a header before using the tool when you need that first record cleaned too.
Completely empty physical lines are skipped while the text is parsed. Records such as ,, still contain fields, so they are counted as data rows and then removed when all fields are empty. The before-and-after counts refer to parsed data records, not physical lines in the original text.
CSV and TSV can contain quoted values with commas, tabs, or line breaks inside a field. The parser keeps quoted content together as one value, then checks the fields in that record. It detects common comma, tab, semicolon, and pipe separators.
Preview and Download the Cleaned CSV
After processing, the summary displays the number of data rows and columns before and after cleanup. The preview is plain CSV text and is shortened at about 7,000 characters for long results. That display limit does not limit the download: Download Cleaned CSV saves the complete processed data.
The output is a separate comma-separated .csv file, including when the input was TSV or TXT. CSV is a text format, so spreadsheet cell formatting, formulas, and multiple worksheets are not included. Your source file is not overwritten.
Questions About Removing Blank CSV Rows
Will the tool remove a row if one cell is blank?
No. Every field in the data row must be empty or whitespace for the row to be removed. A row with one populated field is kept.
Are rows with spaces or tabs considered empty?
Yes. If every cell contains no value or whitespace only, the data row is removed. The tool does not trim values in rows that remain.
Does the tool keep my column headings?
Yes. The first parsed row is always preserved as the header. If the file has no header, its first data record will be treated as the header.
Can I remove rows when a specific column is blank?
No. This tool removes only completely empty rows. It keeps a row if any field contains a value, even when another field is blank.
Why is the row count different from the number of lines in my file?
Completely empty physical lines are skipped while parsing. Records with empty fields, such as ,,, are counted as data rows and then removed if every field is blank.
Can I use TSV or paste text?
Yes. Open CSV, TSV, or TXT files up to 50 MB, or paste delimited text. The cleaned result downloads as CSV.
Does the preview show all of the cleaned data?
For long results, the text preview is shortened to about 7,000 characters. The downloaded CSV contains the complete result.
Are my files uploaded?
No. The selected file is read and processed in your browser. This tool does not send its contents to a server.
Supported Files, Size, and Privacy
The tool accepts CSV, TSV, and plain-text delimited files up to 50 MB. It also accepts pasted data. Files are read and processed in your browser, and their contents are not uploaded. Large files can take longer to read depending on your device.
