    SQLizer offers a straightforward interface that allows users to convert various file formats to SQL quickly and efficiently without needing advanced technical skills.
  • Supports Multiple Formats
    The tool supports conversion from multiple data formats like Excel, CSV, JSON, and XML to SQL, providing flexibility to users with diverse data sources.
  • Time-Saving
    Automates the process of converting data to SQL, reducing the time and effort required compared to manual methods.
  • Web-Based
    Being a web-based tool, it does not require any software installation, making it accessible from any location with internet connectivity.

Possible disadvantages

  • Data Security
    Since SQLizer processes data on their servers, there may be concerns about data security and privacy, especially for sensitive data.
  • Limited Customization
    The tool may have limited customization options for complex data conversion needs, which might not meet all user requirements.
  • Performance
    As a web-based tool, its performance could be affected by internet speed and server load, potentially causing delays for large data sets.
  • Cost
    Depending on the usage volume or required features, there could be costs associated with the service, which might not be viable for all users.
  • Secret Masking
    Redacts API keys, private keys, database URIs, passwords, and PII before prompts leave the device.
  • Prompt Injection Detection
    Blocks direct overrides, DAN and jailbreak personas, system prompt extraction, and hidden Unicode payloads in under 0.2 ms.
  • PII Detection
    Checks Australian TFNs and Medicare numbers, mobile numbers, credit cards, and other identity data before transmission.

Questions & Answers

As answered by people managing SQLizer and PromptShield.

Who are some of the biggest customers of your product?

PromptShield's answer:

  • No publicly disclosed customers yet; PromptShield is an early open-source project, and its public entry points are the GitHub repository and browser demo.

What makes your product unique?

PromptShield's answer:

PromptShield combines two protections in one local-first tool:

  • Outbound protection masks credentials, database URIs, and PII with deterministic pseudonyms, so context stays useful and values can be restored locally.
  • Inbound protection blocks prompt injection, DAN and jailbreak personas, system-prompt extraction, and hidden Unicode payloads.

It uses Python's standard library, zero telemetry, and zero external network calls. The code is open source and there is a live browser demo.

Why should a person choose your product over its competitors?

PromptShield's answer:

Choose PromptShield when protection should stay on the developer's machine. It combines outbound secret and PII sanitisation with inbound prompt-injection defence, uses Python's standard library, makes no external network calls, and has zero telemetry. Deterministic pseudonyms preserve useful context, while the Guard engine is designed for sub-millisecond checks. The project is open source and includes a live browser demo.

How would you describe the primary audience of your product?

PromptShield's answer:

PromptShield is for developers and small teams who send source code, logs, tickets, or customer text to Claude, ChatGPT, Gemini, and other LLMs. It also suits maintainers of LLM agents and RAG pipelines, security and privacy-conscious organisations, and people who use terminal AI tools. It is designed for users who want local, auditable controls without sending sensitive data to a third-party scanning service.

What's the story behind your product?

PromptShield's answer:

PromptShield was created for a practical problem in AI workflows: people can paste secrets and personal data into model prompts, while agent-facing prompts can carry injections and jailbreaks. The project addresses both directions with a local-first Python tool that sanitises outbound data and guards inbound prompts. It grew into an open-source project with a CLI, Git hook, clipboard workflow, CI integration, and browser sandbox. Zero telemetry and a standard-library-only implementation keep deployment simple.

Which are the primary technologies used for building your product?

PromptShield's answer:

The CLI and core engines use Python 3.8+ and the Python standard library. Detection combines secret signatures, pattern matching, entropy checks, Luhn credit-card validation, Australian TFN Mod 11 validation, and heuristics for prompt injection, jailbreaks, system-prompt extraction, and hidden Unicode. The project also includes Git hooks and GitHub Actions integration. The interactive demo runs client-side in the browser with JavaScript and WebAssembly.
