## Overview

The default local parser checks HTML tables, key-value lines, tabs, comma/pipe/semicolon delimiters, and aligned whitespace. Optionally use DeepSeek (deepseek/deepseek-v4-flash-0731) to infer structure from harder pasted data; local type inference and CSV, JSON, and Markdown rendering still run after the AI response is validated. AI mode is limited to 40,000 input characters.

## Inputs

- **Text Input** (textarea): Paste a table, key-value lines, or HTML table...
- **Input Mode** (select)
- **Delimiter** (text): One character, for example ;
- **Header Mode** (select)
- **Trim Cells** (checkbox)
- **Use AI processing** (checkbox)

## When to use

- Convert copied spreadsheet or tab-separated data into a clean table.
- Turn configuration or settings written as key-value lines into one structured record.
- Parse pasted HTML tables or delimited text before using the data in another workflow.

## How it works

- Paste your source text into the Text Input field.
- Choose Auto-detect or select an input mode such as HTML Table, Tab-separated, Delimited, Whitespace columns, or Key-value lines.
- Set a delimiter and header mode when needed, and keep Trim Cells enabled to remove extra surrounding spaces.
- Review the inferred table, typed values, anomalies, and CSV, JSON, and Markdown outputs.

## Use cases

- Clean copied spreadsheet rows and convert them into CSV or JSON.
- Transform application settings and metadata from key-value lines into a typed record.
- Extract structured rows from HTML tables or inconsistent text reports.

## Frequently asked questions

### What input can the tool parse?

It can parse HTML tables, key-value lines, tab-separated text, comma-, pipe-, or semicolon-delimited text, and aligned whitespace columns.

### Can I specify a delimiter?

Yes. Select Delimited input mode and enter a single delimiter character, such as a semicolon.

### How are headers detected?

Header Mode supports Automatic, First row is header, and No header.

### What formats does the tool output?

It provides structured results with CSV, JSON, and Markdown renderings.

### When should I use AI processing?

Enable AI processing for harder pasted data when local auto-detection does not infer the structure reliably. AI mode accepts up to 40,000 input characters.
