PDF to XLSX C# Overview
Convert PDF documents to Excel (XLSX) worksheets with high fidelity for analysis and automation. Preserve tables, text, numbers, and basic formatting to minimize cleanup, and restrict processing to specific page ranges for targeted exports. Handle password‑protected files, select OCR mode/engine and languages to recover content from scans, and output onto a single sheet when desired. Normalize data for pipelines by setting decimal and thousands separators aligned to your locale. Built for batch processing with predictable results.

Customizable Parameters
Fine-tune your automation with these powerful conversion options
File
File Supported formats: .pdfFile to be converted. Value can be URL or file content.
Password
StringSets the password to open protected documents.
PageRange
String Default: 1-2000Set page range. Example 1-10 or 1,2,5.
OcrMode
Collection Default: autoDefines how OCR is applied during conversion. Auto performs OCR only when needed. Force applies OCR to all pages. Never disables OCR entirely.
OcrLanguage
Collection Default: autoConfigure the OCR language for text recognition. If auto-detection fails, manually specify the language.
Values: auto ar ca zh da nl en fi fr de el ko it ja no pl pt ro ru sl es sv tr ua thOcrEngine
Collection Default: nativeSelect the OCR engine to use for text recognition. Each engine may produce slightly different results. If Tesseract is selected, the OcrLanguage property must be explicitly set, as automatic language detection is not supported.
IncludeFormatting
Bool Default: FalseInclude non-table content in an excel file, like images and paragraphs.
SingleSheet
Bool Default: FalseCombine extracted tables into a single sheet.
DecimalSeparator
Collection Default: autoDefines the character used as a decimal separator in numeric values.
- auto (default): Automatically detects the decimal separator based on the formatting within the document.
- period: Forces usage of period (
.) as the decimal separator. - comma: Forces usage of comma (
,) as the decimal separator.
ThousandsSeparator
Collection Default: autoDefines the character used as a thousands separator in numeric values.
- auto (default): Automatically detects the thousands separator based on the formatting within the document.
- period: Forces usage of period (
.) as the thousands separator. - comma: Forces usage of comma (
,) as the thousands separator. - space: Forces usage of space (
StoreFile
Bool Default: FalseWhen the StoreFile parameter is set to True, your converted file is written to ConvertAPI’s encrypted, temporary storage and made available via a time-limited secure download URL, valid for up to 3 hours. After this period, the file is permanently deleted.
When StoreFile is set to False, conversion happens entirely in-memory. The raw file bytes are streamed back in the API response without touching disk or external storage, ensuring maximum security and zero persistence so that only you can access the content.
