Works like `grep` but for Parquet files, with support for recursive directory search and multiple output formats.\n\nBuilt on top of [hyparquet](https://github.com/hyparam/hyparquet) for high-performance Parquet parsing.\n\n## Installation\n\n```bash\nnpm install -g parquet-grep\n```\n\nOr use directly with npx:\n\n```bash\nnpx parquet-grep \"search term\" file.parquet\n```\n\n## Usage\n\n```bash\nparquet-grep [options] \u003cquery\u003e [parquet-file]\n```\n\n### Options\n\n- `-i` - Force case-insensitive search (by default: case-insensitive if query is lowercase, case-sensitive if query contains uppercase)\n- `-v` - Invert match (show non-matching rows)\n- `-m \u003cn\u003e` / `--limit \u003cn\u003e` - Limit matches per file (default: 5, 0 = unlimited). Shows \"...\" when limit is exceeded\n- `--offset \u003cn\u003e` - Skip first N matches per file (default: 0). Useful with --limit for pagination\n- `--table` - Output in markdown table format (default, grouped by file)\n- `--jsonl` - Output as JSON lines (one match per line with filename, rowOffset, and value)\n\nIf no file is specified, recursively searches all `.parquet` files in the current directory, skipping `node_modules` and hidden directories.\n\n### Examples\n\n**Search a single file:**\n```bash\nparquet-grep \"Holland\" bunnies.parquet\n```\n\n**Search recursively in current directory:**\n```bash\nparquet-grep \"search term\"\n```\n\n**Case-insensitive search:**\n```bash\nparquet-grep -i \"HOLLAND\" bunnies.parquet\n```\n\n**JSONL output:**\n```bash\nparquet-grep --jsonl \"Holland\" bunnies.parquet\n```\n\n**Limit results:**\n```bash\nparquet-grep --limit 10 \"search term\" file.parquet  # Show at most 10 matches per file\nparquet-grep --limit 0 \"search term\" file.parquet   # Unlimited matches\n```\n\n**Pagination with offset and limit:**\n```bash\nparquet-grep --offset 5 --limit 10 \"search term\" file.parquet  # Show matches 5-14 (skip first 5)\nparquet-grep --offset 0 --limit 5 \"search term\" file.parquet   # Show first 5 matches\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhyparam%2Fparquet-grep","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhyparam%2Fparquet-grep","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhyparam%2Fparquet-grep/lists"}
