What This CSV Filter Tool Offers
Filter CSV rows by a column value with several match types: exact match, contains (case-insensitive or case-sensitive), starts with, or ends with. Choose the column from a dropdown that shows header names when your file has a header. See how many rows matched (e.g. 12 of 100 total), preview the result in a table (first 25 rows), then download or copy. All processing is client-side—no upload to any server.
- Filter by column value: Select the column (dropdown with header names when available) and enter a value. Rows where that column matches are kept. Empty value keeps all rows.
- Match types: Exact match: column equals value. Contains: column includes value (case-insensitive or case-sensitive). Starts with / Ends with: column begins or ends with the value.
- Column selector with header names: When the first row is a header, the dropdown shows index and name (e.g. 0: Status). Otherwise Column 0, Column 1, etc.
- Row count: After filtering, you see how many rows matched and the original total (e.g. 12 of 100 total).
- Preview table: A table shows the first 25 filtered rows with a sticky header; the full CSV is in a textarea below.
- First row as header: When present, the first row is kept as header and only data rows are filtered.
- Auto or custom delimiter: Choose Auto to detect the delimiter or pick comma, semicolon, tab, or pipe.
- Encoding for file upload: Select UTF-8, Windows-1252, or ISO-8859-1 when uploading a file.
- Client-side and private: Filtering happens in your browser; nothing is sent to a server.
Why Filter CSV?
Filtering keeps only rows that match a condition (e.g. status, category, or text pattern) before analysis, import, or sharing. Contains and starts/ends with help when you do not need an exact value. The column dropdown with header names makes it easy to pick the right field.

When to Use Each Match Type
- Exact match: Use when the column must equal the value exactly (e.g. status = Active).
- Contains (case-insensitive): Use to find rows where the column includes the text anywhere (e.g. name contains "john").
- Contains (case-sensitive): Same as contains but A and a are different.
- Starts with / Ends with: Use when you know the beginning or end of the value (e.g. code starts with "AB").
Frequently Asked Questions
What match types are available?
Exact match: column value must equal the filter value. Contains (case-insensitive or case-sensitive): column must include the value. Starts with: column must begin with the value. Ends with: column must end with the value. Leave the value empty to keep all rows.
What is Exact match vs contains?
Exact match keeps only rows where the column value equals the filter value exactly. Contains keeps rows where the column value includes the filter value; you can choose case-insensitive (default) or case-sensitive.
What does the column dropdown show?
When your CSV has a header row, the dropdown shows column index and header name (e.g. 0: Status, 1: Name). Otherwise it shows Column 0, Column 1, etc.
What delimiters are supported?
You can use Auto to detect from the first line, or choose comma, semicolon, tab, or pipe.
