CSV Viewer & Editor
Paste CSV data to view, edit, sort, filter, and export as CSV, JSON, TSV, or Markdown.
What Is a CSV Editor?
A CSV editor is a tool that lets you view, edit, sort, filter, and export CSV (Comma-Separated Values) data in a structured table format. Unlike opening CSV files in a text editor where you see raw delimited text, a dedicated CSV editor parses the data into rows and columns — making it easy to inspect, modify, and work with tabular data.
CSV is one of the most universal data formats. Databases export it, spreadsheets produce it, APIs return it, and virtually every programming language can parse it. But working with raw CSV text is error-prone — misplaced commas, unescaped quotes, and inconsistent delimiters can silently corrupt your data. A proper CSV viewer catches these issues and lets you work with the data visually.
Our online CSV editor handles all the edge cases: quoted fields, escaped quotes, different delimiters (comma, semicolon, tab, pipe), and mixed column counts. You can edit cells inline, add or delete rows and columns, sort and filter data, then export to CSV, JSON, TSV, or Markdown — all directly in your browser with no data ever leaving your machine.
How to Use This CSV Editor
- Paste your CSV data — Copy your CSV content into the input area. The editor auto-detects the delimiter (comma, semicolon, tab, or pipe), or you can select one manually.
- Configure parsing options — Toggle "First row as header" if your CSV includes column headers. Choose a custom delimiter if needed.
- Click "Parse CSV" — The editor parses your data into an interactive table with sortable columns, inline editing, and row filtering.
- Edit your data — Click any cell to edit it inline. Use the "+ Row" and "+ Column" buttons to add data. Delete rows or columns with the ✕ buttons.
- Export your results — Copy the edited data as CSV, JSON, TSV, or Markdown with a single click. Switch to Raw View to see and edit the raw text directly.
Key Features
- Auto-detect delimiters — Automatically identifies whether your data uses commas, semicolons, tabs, or pipes as separators.
- Inline cell editing — Click any cell in the table to edit its value directly. Changes are reflected immediately in the raw data.
- Sort and filter — Click column headers to sort alphabetically or numerically. Use the search box to filter rows by any value.
- Add and delete rows/columns — Modify the structure of your data with one-click row and column operations.
- Multi-format export — Export your data as CSV, JSON (with headers as keys), TSV, or Markdown tables.
- Table and Raw views — Switch between a visual table editor and raw text editing for maximum flexibility.
- 100% client-side — Your data never leaves your browser. No uploads, no server processing, no tracking.
Common Use Cases
- Cleaning up database exports — Fix malformed rows, remove empty columns, and normalize data from SQL exports before importing into another system.
- Converting CSV to JSON — Transform CSV data into JSON format with headers as object keys — perfect for API payloads or configuration files.
- Quick data inspection — Paste a CSV snippet from logs, APIs, or spreadsheets to quickly visualize and understand the data structure.
- Preparing Markdown tables — Convert CSV data into Markdown table format for documentation, README files, or blog posts.
- Editing configuration data — Modify CSV-based configuration files (translations, feature flags, pricing tables) with a visual editor instead of error-prone text editing.
