Free, privacy-first TXT to JSON converter. Transform TXT files to JSON format directly in your browser. No uploads, no servers, no sign-up.
Each row from your text file becomes one JSON object per line. NDJSON is easy to stream, grep, and pipe into tools like jq, Python, or BigQuery.
Your TXT file stays on your device. No data is sent to any server. Everything runs locally in your browser using DuckDB WASM.
Tabs, pipes, semicolons, fixed-width -- ExploreMyData figures out the delimiter and parses your text into structured columns automatically.
Filter rows, rename columns, aggregate data, or add calculated fields. Shape your text data before converting it to JSON.
No sign-up, no trial, no watermarks. Convert as many TXT files to JSON as you need, completely free.
