Question 1

How do I convert CSV to JSON?

Accepted Answer

Simply drop your CSV file into the converter above, and Diakrio will automatically detect the delimiter and column structure. The CSV rows are streamed and converted into JSON objects. You can download the result as a JSON array or NDJSON stream.

Question 2

Can I convert large CSV files to JSON?

Accepted Answer

Diakrio parses CSV incrementally and, in supported browsers, writes output chunks directly to disk. Practical limits still depend on record size, transforms, browser overhead, disk space, and the destination. Live metrics show MB/s, records/s, and observed resource use.

Question 3

What CSV formats are supported?

Accepted Answer

Diakrio auto-detects common CSV dialects including comma, semicolon, tab, and pipe delimiters. It also handles quoted fields, escaped characters, and various line endings (LF, CRLF). Custom delimiters can be specified manually.

Question 4

Is the converted JSON downloadable?

Accepted Answer

Yes. Supported browsers save output directly while conversion runs. The compatibility fallback buffers output up to a documented safety limit before enabling download or copy.

Question 5

Why use Diakrio instead of online CSV converters?

Accepted Answer

Diakrio runs entirely in your browser using WebAssembly, so your data never leaves your device. Its streaming and direct-save path avoids building a second full output Blob; actual speed and capacity depend on your data, browser, and device.
