Frequently Asked Questions

Everything you need to know about Data Format Converter

Which conversions are supported?

Six formats in (JSON, YAML, CSV, TSV, XML) and six out (JSON, YAML, CSV, TSV, XML, SQL INSERT). That's 30 conversion pairs. SQL is output-only since INSERT statements aren't a structured input format. TOML support is planned.

Is my data uploaded anywhere?

No. Parsing, conversion and file reading all happen in your browser. Drag a 50 MB CSV — it parses locally without touching any server. Safe for confidential data.

How does the CSV parser handle quoted commas and newlines inside fields?

RFC 4180 — fields containing commas, newlines or double quotes must be wrapped in double quotes. Escape an embedded double quote by doubling it (`""`). The parser handles all three cases automatically.

What's the YAML behavior for date strings?

We use js-yaml's default safeLoad — ISO 8601 strings without explicit quoting are parsed as Date objects. Wrap them in single quotes (`'2026-05-19'`) if you want them to stay as strings in the output.

Can I generate INSERT statements for a specific table name?

Right now the table name defaults to `my_table`. A per-row column-aware INSERT builder with custom table name and CREATE TABLE generation is on the roadmap. For now, find-replace `my_table` in the output.
