• View all object stores within a database
• Query data using SQL-like WHERE clauses

• View results in a formatted JSON display

Given data like:

{ "symbol": "ID_42140878", "timestamp": 1766358000000000, "sequence": 0, "price": 6905.75, "open": 6906.25, "high": 6910, "low": 6900.5, "close": 6905.75, "volume": 0, "date": "2025-12-21T23:00:00.000Z", "chartId": "ID_42140878_volume_20000" }

You can write queries like:

Simple equality:

symbol = 'ID_42140878'

Date range:

date >= '2025-12-01' and date < '2025-12-15'

Troubleshooting

• No databases found: Make sure you're on a page that uses IndexedDB
• Permission denied: Some websites may have strict Content Security Policies
• Extension not loading: Check the Browser Console (Ctrl+Shift+J) for errors

symbol = 'ID_42140878' and date >= '2025-12-01' and date < '2025-12-15'

Numeric comparisons:

price > 7000 and volume < 1000

BETWEEN operator:

price between 6800 and 6900

Complex query with date range and price range:

date >= '2025-11-01' and date < '2025-12-01' and price between 6800 and 6900

OR operator:

price > 7000 or volume > 10000

Nested properties (dot notation):

user.name = 'John' and user.age >= 18

Supported Operators

• Comparison: =, !=, <>, >, <, >=, <=
• Logical: AND, OR
• Range: BETWEEN x AND y

The query parser automatically handles:

• Strings: Enclosed in single or double quotes ('value' or "value")
• Numbers: Plain numeric values (123, 45.67)
• Booleans: true, false
• Null: null
• Dates: Strings that can be parsed as dates are automatically compared as dates
