Sorun Giderme

Extra empty objects appear at the end of the JSON array

Çözüm

This is caused by trailing newlines in the CSV. Remove any blank lines at the end of your CSV before converting.

Fields with commas are split incorrectly

Çözüm

Fields containing commas must be wrapped in double quotes in the CSV (e.g., "New York, NY"). Ensure your source data is properly quoted per the CSV standard.

Numbers appear as strings in the JSON output

Çözüm

The converter outputs all values as strings for safety. If your application requires numeric types, parse the strings in your code using parseInt() or parseFloat() after importing.

Sıkça Sorulan Sorular

What delimiter is used?

The tool expects comma-separated values (CSV). Tab-separated (TSV) and semicolon-separated files are not currently supported. If your file uses a different delimiter, replace it with commas before converting.

How are numbers and booleans handled?

All values are output as JSON strings. Type conversion is not applied automatically — if you need numeric or boolean types, parse the output in your application code.

What happens if a field contains a comma?

Fields containing commas must be enclosed in double quotes in the CSV (e.g., "value with, comma"). The parser correctly handles RFC 4180-compliant quoted fields.

What if my CSV has no header row?

The first row is always treated as the header row. If your CSV has no headers, manually add a header row with column names before pasting it into the tool.

Can I convert a CSV file directly?

Yes, you can paste CSV content directly or, if a file upload option is available, load the file from your device. No data is sent to a server — the conversion runs entirely in your browser.

What is the maximum CSV size I can convert?

There is no server-imposed limit. The practical limit depends on your browser's memory. CSVs with tens of thousands of rows typically convert in under a second on modern hardware.

How do I handle CSV with special characters?

The tool handles UTF-8 encoded CSV, including accented characters, emoji, and other Unicode characters. Ensure your source CSV is saved as UTF-8 to avoid encoding issues.

Is my data sent to a server?

No. All processing is done entirely in your browser. Your CSV data never leaves your device and is not stored or logged anywhere.
