FAQs

What is Flexter in simple terms?

Flexter is a no-code tool that automatically converts complex XML and JSON files into clean, structured tables for databases and analytics—no manual coding required.

What problem does Flexter solve?

It eliminates the slow, costly, and error-prone task of manually parsing nested XML/JSON data using code or traditional ETL tools.

How is Flexter different from standard ETL tools?

Unlike general-purpose ETL tools with basic semi-structured support, Flexter is purpose-built for XML and JSON. It automates schema detection, mapping, and parallel processing at scale.

Is Flexter No-Code or Low-Code?

Flexter is fully No-Code for data conversion. Some light scripting may be used for integration, but the core processing requires no coding.

Can Flexter handle large data volumes?

Yes, Flexter is designed to process millions or even billions of files in parallel using horizontal scalability and distributed workloads.

Can it handle very large files?

Yes, Flexter is optimised for huge individual files (multi-GB XML/JSON) using memory-efficient parsing techniques.

Does Flexter support industry standards like HL7, FHIR, ISO 20022?

Yes, Flexter supports any XML/XSD format and is fully compliant with the XSD specification.

Do I need an XSD schema?

No. Flexter works with or without an XSD. If available, it uses the XSD; otherwise, it infers the structure automatically.
