Export Excel / CSV / JSON
CSV is plain text — data only, no formatting, formulas or multiple sheets — light and universal for import/export; xlsx supports sheets, formulas and styles. Choose xlsx for formatting, CSV for portability, and convert either way in WUJIEE Doc Tools.
Garbling comes from encoding mismatches (UTF-8 vs GBK/ANSI). WUJIEE Doc Tools exports CSV with a BOM so Excel reads non-Latin text correctly; pick the matching encoding for whichever program you hand it to.
The tool detects the PDF's table lines and cell structure to rebuild rows and columns. Clean grids restore well; merged cells, cross-page tables and borderless ones need touch-ups, and text-based beats scans (run OCR on scanned tables first).
In WUJIEE Doc Tools conversion is processed locally and your data is destroyed when you close the page, so financial reports, client lists and data tables never leave your device.
