CSV Viewer

CSV Viewer is a data inspection tool that runs in the browser and focuses on accurate parsing, quick validation, and straightforward export of CSV data without coding. It handles common CSV dialects, quoted fields, and large files through streaming where available. The tool is designed for analysts, engineers, QA teams, and product owners who receive CSV exports from APIs, databases, or logs and need a reliable, reproducible view of the data.

Conceptually, you provide CSV content or upload a file and the parser detects the delimiter, identifies the header row, and renders a tabular view with counts and sample rows. Users can search within columns, sort by values, and apply lightweight filters to isolate records of interest. The system emphasizes data integrity by highlighting rows with inconsistent field counts.

Unique value and differentiators include robust dialect support, streaming parsing to handle large files, and flexible export options to CSV or JSON. The tool does not transform data; it exposes a faithful, queryable copy of the input, aiding data validation, sampling, and quick QA checks. It complements pipelines by enabling rapid, repeatable checks without code.

Use cases cover data validation before import, log analysis, API payload review, and dataset sampling for collaboration. The audience includes data scientists, engineers, testers, and product teams who require auditable views of CSV content. The feature set focuses on correctness, speed, and portability across environments.
