Frequently Asked Questions
What file formats does this tool support?
Currently supports CSV, JSON, and XML. CSV is ideal for spreadsheets, JSON for APIs and JavaScript apps, XML for enterprise/SOAP applications. Conversions between any of these three formats are supported.
How does it handle CSV to JSON conversion?
CSV headers become JSON keys. Each row becomes an object. Example: CSV "name,age" / "John,30" becomes JSON {"name":"John","age":"30"}. Perfect for importing CSV data into web apps.
What about encoding and special characters?
The tool handles UTF-8 encoding and escapes special characters (quotes, newlines, unicode) correctly in each format. No data corruption or encoding mismatches.
Can I convert large files?
Yes, but very large files (100MB+) may be slow depending on your browser's memory. For production bulk conversions, use command-line tools (jq, xq, csvkit) or proper backend processing.
Does the tool validate my data?
It parses and re-formats your data, which catches structural errors (malformed JSON, invalid XML). Logical errors (missing fields, wrong values) are not validated; you must review the data.
What if my CSV has quoted fields with commas?
The tool respects standard CSV quoting rules. Fields enclosed in quotes preserve commas inside them. Example: "John, Jr.",30 treats the comma as part of the name, not a delimiter.
How do I preserve data types during conversion?
JSON conversion auto-detects types: unquoted numbers remain numbers, booleans stay booleans. CSV and XML treat everything as text, so you may need to handle type conversion manually post-conversion.
Can I convert batch files?
This tool converts one file at a time. For batch processing, use command-line tools: jq/xq for transformations, csvkit for CSV operations, or write a quick Python/Node.js script.
