Bridging the Gap Between Tabular Spreadsheets & REST APIs
While data analysts and business teams rely on Excel and Google Sheets CSV exports, web developers and database engineers work natively with JSON (JavaScript Object Notation). Converting tabular data into clean JSON schemas is essential for modern web application pipelines.
Handling Edge Cases in CSV to JSON Parsing
- Delimiter Handling: Correctly detecting commas, semicolons, and tab delimiters without breaking on internal comma-containing strings.
- Type Inference: Automatically converting numeric strings into JavaScript numbers and 'true/false' strings into real booleans.
- Header Key Sanitization: Stripping illegal characters and trimming whitespace from JSON object keys.
