Frequently asked questions
How do JSON formatting and validation differ?
Formatting makes valid code readable. Validation locates syntax issues. Business rules require additional checks.
What matters when converting CSV to JSON?
Check delimiters, headers, and quoting. Review the preview before using the generated file.
Can I convert scanned PDFs to Word here?
No. The PDF toolkit manipulates pages, including merging and splitting. It does not include OCR or Word conversion.
Is Base64 encryption?
No. Base64 is a reversible encoding. It does not protect confidentiality or control access.
Why are file size and nesting limited?
Local processing consumes memory. Tool-specific limits reduce excessive load and are shown in the interface.
