COMMON QUESTIONS

Frequently Asked Questions

Data serialization and mapping rules explained
? How does the PDF to JSON converter work?
It unpacks PDF stream dictionaries, scanning text segments and coordinate coordinates to construct structured object elements.
? Are my private PDF documents sent to external databases?
Absolutely not. The parsing loop, text analysis, coordinate mapping, and JSON compile run entirely locally. Your data remains secure.
? What is the difference between 'Raw Text' and 'Tabular Grid' formats?
Raw Text extracts simple paragraph string blocks. Tabular Grid parses column alignments, compiling cells into rows of key-value maps.
? Does the converter support scanned PDF images?
This tool requires vector-native text characters. For image PDFs, OCR tools are required to extract raw text characters first.
? Can I select custom key names for table fields?
Yes, you can edit header cells in the grid preview to set custom JSON object key labels before compiling.
? What is the size limit for JSON files?
There is no specific file size limit. However, massive PDFs (over 100 pages) may take several seconds to process depending on your CPU speed.
