This page is meant for plain comma-separated rows where the first line is the header list and every later line is one record. That covers many copied spreadsheet snippets, small exports, and browser-side fixture tasks where you need a JSON array quickly and do not want to open a script or data notebook.
The current parser stays strict and simple. It splits rows directly on commas, trims each cell, uses the first row as keys, and leaves every value as a string. It does not support quoted commas, multiline cells, tabs, semicolons, or automatic number and boolean typing.
Each data row becomes one object inside a JSON array. Because the workflow is a direct comma split, the safest inputs are clean header-based CSV blocks where commas are the real separators and there are no embedded commas inside field values.
| Example | Value |
|---|---|
| Input | A short CSV block with one header row and simple comma-separated values. |
| Output | A JSON array where every cell is preserved as plain string text. |
If your CSV depends on quoting rules, embedded commas, or spreadsheet quirks, this page is too small for that job. It is more honest as a header row csv to json utility than as a promise that every CSV dialect will round-trip correctly. When the source is messy, use a fuller CSV parser before trusting the JSON output.
No. The current page splits directly on commas and does not implement full quoted-field parsing.
No. Every cell stays a string in the current browser workflow.
No. This page expects commas only.
It is useful when the CSV is already clean, flat, and header-based, and you only need a fast JSON array for the next step.
