Converting raw CSV spreadsheets into valid JSON is essential for feeding databases and REST APIs.
1. Delimiter Auto-Detection
The parser analyzes the first 5 rows to statistically detect the primary separator:
- Comma (
,) - Semicolon (
;) - Tab (
\t) - Pipe (
|)
2. Type Inference Engine
Since CSV is pure un-typed text, the engine inspects values against regex patterns:
| Raw CSV Value | Inferred JSON Type | Parsed Output |
|---|---|---|
"42" | Integer (number) | 42 |
"3.1415" | Float (number) | 3.1415 |
"true" / "TRUE" | Boolean (boolean) | true |
"null" / "NULL" / "" | Null | null |
"2026-08-16T12:00:00Z" | String (ISO Date) | "2026-08-16T12:00:00Z" |
