CSV to JSON Converter
Convert header-based CSV into readable JSON so you can inspect rows, validate assumptions, and move messy spreadsheet data into developer workflows faster.
Use semicolon or tab when the export does not use commas.
Useful for spreadsheet exports when you do not want to paste large files manually.

This table shows how the current delimiter and headers are being interpreted so you can catch broken exports before producing JSON.
| id | name | active |
|---|---|---|
| 1 | Ana | true |
| 2 | Luis | false |
Use this when tabular data is blocking debugging
CSV is convenient for handoff but awkward to reason about when the real question is row shape, field types, or missing values.
Convert CSV before writing import scripts so you can validate field names and record shape with fewer blind assumptions.
JSON makes duplicate columns, empty values, and inconsistent rows easier to spot before they reach your backend.
If the next step is mock payloads, tests, or fixtures, converting to JSON gives you a better starting point than keeping everything in CSV.
What this conversion does for you
The goal is not just format change. It is making row-level problems obvious enough to act on.
Values such as true, false, null, or simple numbers are converted so the JSON is easier to review without post-processing every field.
Quoted commas, line breaks, and escaped quotes are preserved so normal spreadsheet exports do not break immediately.
If a row has the wrong number of columns, the tool fails early instead of silently producing misleading JSON.
You can switch between comma, semicolon, tab, or pipe so spreadsheet exports from different locales do not need manual cleanup first.
