Pro Tips for Best Results
💡 Optimize Before Uploading
If your documents contain high-resolution camera scans, using dedicated tools like our PDF Compressor or Image Compressor can reduce total payload size by over 80% without visible degradation.
⚡ Always Verify File Constraints
Most online portals reject files exceeding 2MB or 500KB. Keep your outputs under the target ceiling to prevent submission timeout errors.
Frequently Asked Questions (FAQ)
Q: How do I handle nested JSON objects when converting to Excel?
TARGETROOT automatically flattens nested JSON hierarchies using dot-notation column headers (e.g. user.address.city), producing clean, analysis-ready Excel spreadsheets.
Q: Will numbers and booleans be converted properly to Excel cell types?
Yes! Numeric strings and numbers are typed as native Excel integers and floats, preventing Excel from flagging numbers as green triangle text warnings.
