CSV to JSON Converter
Paste CSV text and convert it into a JSON array without uploading files or storing raw data in custom analytics.
Convert CSV rows into a JSON array for quick development, testing, migration prep, and data cleanup tasks without uploading your data.
Result
How it works
Paste CSV text, choose the delimiter, choose whether the first row should become JSON keys, and run the conversion in the browser. SOLVEOZA returns formatted JSON plus row and column counts. This first implementation is intentionally conservative: it keeps text processing local, avoids server uploads, caps large inputs, and keeps analytics coarse so raw CSV, JSON output, filenames, headers, and row values are not stored.
Examples
Name and score table
Input: name,score Ada,10 Linus,8
Output: [{"name":"Ada","score":"10"},{"name":"Linus","score":"8"}]
Generated columns
Input: Ada,10 Linus,8
Output: [{"column1":"Ada","column2":"10"},{"column1":"Linus","column2":"8"}]
Tab-delimited values
Input: name score Ada 10
Output: [{"name":"Ada","score":"10"}]
Semicolon-delimited values
Input: city;country Seoul;KR
Output: [{"city":"Seoul","country":"KR"}]
Quoted comma
Input: name,note Ada,"fast, careful"
Output: [{"name":"Ada","note":"fast, careful"}]
Escaped quote
Input: name,note Ada,"said ""hello"""
Output: [{"name":"Ada","note":"said \"hello\""}]
Empty cells
Input: name,note Ada,
Output: [{"name":"Ada","note":""}]
FAQ
Does SOLVEOZA upload my CSV file?
No. This first CSV to JSON tool runs in the browser tool flow. CSV text and local file bytes are not sent to a SOLVEOZA conversion server.
Does SOLVEOZA store filenames?
No. The privacy contract forbids storing filenames in analytics, logs, URLs, metadata, or error messages for this tool.
Does SOLVEOZA store pasted CSV text?
No. Custom analytics may record only coarse tool events and safe buckets, not raw CSV, headers, row values, or JSON output.
What happens with malformed CSV?
The tool returns a generic validation message such as a quoting or row-width issue without echoing the private input value.
Can I use the first row as JSON keys?
Yes. The default mode uses the first row as headers. A generated-column mode can create column1, column2, and similar keys.
Which delimiters are supported?
The first slice supports comma, tab, semicolon, and pipe delimiters for common CSV and TSV cleanup tasks.
Can I convert very large files?
Not in this first slice. The browser safety limit is 512 KiB input, 5,000 rows, 100 columns, and 2 MiB generated JSON output.
Are spreadsheet formulas executed?
No. Formula-like values are preserved as strings in JSON. The converter does not evaluate spreadsheet formulas or expressions.
