Frequently Asked Questions

Does this work with Excel-exported CSV?

Yes. Excel-exported CSV files use standard comma separation and RFC 4180 quoting, which DevConvert handles correctly including quoted fields with commas and escaped double-quotes.

Are number strings converted to numbers in JSON?

Currently all CSV values are treated as strings in the JSON output to avoid incorrect type coercion. Cast the values to numbers in your application code after importing.

What delimiter does this support?

DevConvert auto-detects commas. Tab-separated values (TSV) are also supported — paste them and the converter will parse them correctly.
