CSV Row Filter: Extract Exactly the Rows You Need
Large CSV exports contain rows you do not need. Instead of loading the file into Excel or writing a script, use this tool to filter rows by any column — keep only Engineering department rows, rows where salary is greater than 90000, or emails that start with a specific prefix.
Eight Filter Operators
Contains and not contains do a case-insensitive substring match. Equals and not equals do a case-sensitive exact match. Starts with and ends with check the beginning or end of the cell value. Greater than and less than compare cell values as numbers — rows where the cell is not a valid number are excluded when using these operators.
String vs Numeric Operators
String operators (contains, equals, starts with, ends with) treat all cell values as text. Numeric operators (greater than, less than) parse cell values as JavaScript numbers. If a cell value is not parseable as a number, that row does not pass the numeric filter — it is excluded from results rather than causing an error.
Chaining Filters
This tool applies one filter at a time. To apply multiple filters — e.g. department equals Engineering AND salary greater than 90000 — apply the first filter, copy the output, paste it back as input, then apply the second filter. This sequential approach is simple and keeps the UI predictable.
Practical Examples
Extracting High-Value Customer Rows
From a CRM export, find customers with lifetime value over $10,000.
- 1.Paste the CSV with a lifetime_value column
- 2.Select 'lifetime_value' as the filter column
- 3.Choose 'Greater than' operator and enter '10000'
- 4.Copy the filtered rows for targeted outreach or analysis
Filter Operators
- Contains / Not contains — case-insensitive substring match
- Equals / Not equals — case-sensitive exact match
- Starts with / Ends with — prefix or suffix match
- Greater than / Less than — numeric comparison
Good Use Cases
- Filtering employee exports by department or location
- Extracting orders above a revenue threshold
- Finding email addresses from a specific domain
- Isolating log rows containing a specific error code
Frequently Asked Questions
Is the filter case-sensitive?
String operators (contains, not contains, starts with, ends with) are case-insensitive. Equals and not equals are case-sensitive exact matches.
How do greater than and less than work?
These operators compare cell values as numbers. If either the cell or the comparison value is not a valid number, the row is excluded from results.
Can I apply multiple filters?
This tool applies a single filter at a time. For multiple filters, apply sequentially — copy the output and paste it back as input to apply the next condition.
