About Query String Parser
Query String Parser extracts URL parameters into JSON or builds an encoded query string from a JSON object.
Repeated keys are preserved as arrays so filters, tags and multi-select parameters are not silently lost.
When to use Query String Parser
- Inspect campaign, search or API URL parameters.
- Build an encoded query string from test values.
- Find repeated keys in a long URL.
How to use Query String Parser
- Enter the code, identifier, URL or expression required by Query String Parser.
- Choose the relevant parsing, formatting, generation or encoding options.
- Review errors and inspect the complete output before adding it to a project.
- Copy or download the result, then validate it in the target runtime when production behavior matters.
Real-world examples
- Parse a search URL containing repeated tag parameters into JSON.
- Build a query string from a JSON object containing a search term, page and filter array.
Tips for better results
- Use decoded JSON for inspection but keep percent encoding in real URLs.
- Confirm whether the receiving application expects repeated keys, comma-separated values or bracket notation.
Common mistakes to avoid
- Query strings do not preserve original data types; numbers and booleans are strings after parsing.
- Do not place secrets in URLs because they may appear in logs and browser history.
Privacy and accuracy notes
Inputs are designed to be processed in the browser wherever the workflow allows. For sensitive material, review the page, your browser environment and your own data-handling rules before using any online tool.
For professional work, treat Query String Parser as a practical helper rather than the final authority. Check the source data, selected options and expected format before using the output in a live project.
