File limitations and processing

AI Hub enforces these maximum resource limits for files.

Single file: 50 MB or 800 pages

Total upload size: 100 MB
Conversations: 100 files
Automation projects: 500 files
Automation app runs: 1,000 files

Supported file types

These file types are supported for import.

.bat, .bashc, .c, .cc, .chtml, .cmake, .cmd, .cpp, .cs, .css, .csv, .cxx, .cy, .dockerfile, .doc, .docx, .eml, .gdoc, .go, .gsheet, .gslides, .h++, .hpp, .html, .java, .jpeg, .jpg, .js, .json, .mht, .mhtml, .mkfile, .msg, .pdf, .perl, .php, .plsql, .png, .pptx, .py, .pxi, .pyx, .r, .rd, .rs, .rtf, .ruby, .tif, .tiff, .ts, .txt, .xls, .xlsx, .xml, .yaml, .yml, .zsh

When browsing connected Google Drives, native Google file types (.gdoc, .gsheet, .gslides) are displayed in the file explorer but the files are converted to PDF when imported.

In commercial and enterprise automation projects with file splitting enabled, multipage files can include multiple documents. For best results in all other projects and conversations, use one file for each document.

App run results can be exported in CSV or Excel format.

For images, higher resolution provides better digitization results. Aim for a minimum scanning or capture resolution of 300 DPI.

Digitization details

When you upload files to AI Hub, the default digitization process includes these steps.

Modifying digitization settings for your conversation or project can impact these steps.

Email attachments are separated and treated as individual files. Inline images are treated as part of the email body.
Google Drive files are converted to PDF.
PDF layers are flattened to include all text and image elements.
Optical character recognition (OCR) is performed on both typed and handwritten text.
Page rotation, skew, and warp are corrected.
Signatures, checkboxes, and barcodes—both numeric and non-numeric formats—are detected, and appropriate markers are added to the text space.

Spreadsheet limitations

Excel spreadsheets and CSV files are subject to these limitations.

Excel files are processed in their native format, unless you disable Process spreadsheets natively in digitization settings for your conversation or project. Native processing offers better results for wide tables, but doesn’t support embedded objects, such as charts, or source highlighting in results.

Upload limitations

Files must be less than 10 MB.
Files can contain one large table up to 400 columns. Excel files can contain multiple small- to medium-sized tables on one sheet (totaling 200 rows and 30 columns).

Extraction limitations

Total extracted results are limited to 80,000 cells, for example:

If extracting 400 columns, you can retrieve up to 200 rows (400 × 200 = 80,000).
If extracting 10 columns, you can retrieve up to 8,000 rows (10 × 8,000 = 80,000).

You can adjust the number of columns and rows as needed within the 80,000 cell limit.

Unsupported features

Advanced features such as macros and data validation.
Triangular or nested tables.
Tables with multi-row or frozen headers.
Tables with empty rows or columns.
