Complete CSV Filter Guide

CSV filtering is the process of selecting only the rows from a CSV file that match specific conditions on one or more columns. It is analogous to a SQL WHERE clause or a spreadsheet filter -- you define a condition, and only rows satisfying that condition appear in the output. The header row is always preserved.

Our free online CSV filter tool supports 10 operators covering text matching (equals, contains, starts with, ends with), negation (not equals, not contains), numeric comparison (greater than, less than), and presence checks (is empty, is not empty). All text comparisons are case-insensitive for maximum flexibility.

Filtering is a non-destructive operation. Your original data is never modified. The tool produces a new CSV containing only the matching rows, which you can copy to your clipboard or further process with our other CSV tools such as Sort, Column Picker, or format converters.

Equals / Not Equals: Exact match comparison. "Equals" returns rows where the cell value exactly matches the filter value (case-insensitive). "Not Equals" returns all other rows. Useful for selecting or excluding specific categories, statuses, or identifiers.

Contains / Not Contains: Substring matching. "Contains" returns rows where the cell value includes the filter text anywhere. "Not Contains" returns rows without the substring. Ideal for partial text searches across names, descriptions, or addresses.

Starts With / Ends With: Positional matching. Check if cell values begin or end with specific text. Useful for matching prefixes (country codes, product SKUs) or suffixes (file extensions, domain names).

Greater Than / Less Than: Numeric comparison. Both the cell value and filter value must be valid numbers. Non-numeric cells are excluded from results. Use these operators for threshold filtering -- scores above 90, prices under 50, ages over 18, and similar conditions.

Data Extraction

Extract rows for a specific region, product category, or time period from large CSV datasets for focused analysis.

Quality Control

Find rows with empty required fields using "Is Empty", or locate outliers with "Greater Than" and "Less Than" operators.

Record Lookup

Quickly find specific records by filtering on ID, name, email, or any identifier column using the Equals operator.

Report Generation

Create subset reports by filtering for specific departments, date ranges, or status values before converting to other formats.

Chain filters: Apply one filter, copy the result back as input, and apply a second filter with a different condition. This lets you create AND logic -- for example, filter by city first, then filter the result by age range.

Use Contains for fuzzy matching: When you are not sure of exact values, "Contains" is more forgiving than "Equals". Searching for "york" will match "New York", "New York City", and "Yorkshire".

Find data quality issues: Use "Is Empty" to find rows with missing data in required columns. Use "Not Contains" to find rows missing expected keywords or patterns.

Combine with other tools: After filtering, use CSV Sort to order the results, Column Picker to select relevant columns, or convert to JSON/SQL for further processing.

How do I filter CSV rows by a column value?

Paste your CSV data, select the column to filter by, choose an operator (equals, contains, greater than, etc.), enter a filter value, and click Filter. Only rows matching the condition are included in the output.

What filter operators are available?

We support 10 operators: Equals, Not Equals, Contains, Not Contains, Starts With, Ends With, Greater Than, Less Than, Is Empty, and Is Not Empty. These cover the most common filtering needs.

Is the filtering case-sensitive?

No, all text comparisons are case-insensitive. Filtering for 'new york' will match 'New York', 'NEW YORK', and 'new york'.

How does the Greater Than operator work?

Greater Than performs numeric comparison. Both the cell value and filter value must be valid numbers. Non-numeric values are excluded from the results.

What happens to the header row when filtering?

The header row is always preserved in the output. Only data rows are evaluated against the filter condition.

Can I apply multiple filters?

You can apply one filter at a time. To chain filters, filter once, then paste the filtered output back as input and apply a second filter.

What does the Is Empty operator do?

Is Empty matches rows where the selected column has an empty value (blank cell or whitespace only). No filter value input is needed for this operator.

Is my data secure when filtering online?

Yes, all filtering happens locally in your browser. Your CSV data never leaves your device or gets sent to any server.

Can I filter CSV with quoted fields?

Yes, the parser correctly handles quoted fields containing commas, newlines, and escaped quotes before applying the filter.

How do I filter for rows NOT containing a value?

Use the Not Contains operator. It returns all rows where the selected column does not contain the specified text.

Can I filter by numeric ranges?

Use Greater Than and Less Than operators for range filtering. Apply one condition, then filter the result with the second condition.

How many rows can the filter handle?

There is no hard limit. Filtering is fast even for files with tens of thousands of rows since it runs entirely in your browser.
