Screenshot to Parquet: Save a Table Image as a Parquet File
Parquet is the file analytics tools like. Here is how to get a table that only exists as a picture into one.
Parquet is a compact, fast format used by data tools such as pandas, Spark and DuckDB. It stores the type of each column, so numbers stay numbers. A picture of a table has none of that, so it must be read first.
Screenshot to Data reads the image with OCR in your browser and shows the table for you to check. When it looks right, choose Parquet. Whole numbers, decimals, true/false values and dates are detected and saved with the matching type, and everything else is saved as text.
Before you download, drag a box around only the table, click Read selected area and fix wrong cells. A single stray letter in a number column turns that whole column into text, so check the numeric columns.
Open the file in your tool afterwards and look at the column types. If a column came in as text when you expected numbers, find the odd value with the Data Profiler, fix it in Data Transformation, then save again.
Everything runs on your device. The image and the file are never uploaded.

Frequently asked questions
Is my image uploaded?
No. Only the OCR engine is downloaded once; your image stays on your device.
Does it read handwriting?
No, only printed or on-screen text.
Are numbers and dates kept as numbers and dates?
Yes. Each column gets a type you can change: currency like $1,234.50 and accounting negatives like (300) become numbers, and dates become real dates in Excel and Parquet. Codes with leading zeros and phone numbers stay text.
What is the second reader?
The first reader is fast and handles most screenshots. When it is unsure (a photo of a screen, small text, glare), a second reader, PaddleOCR, double-checks the unsure words. It runs on your device, and the first time it downloads about 16 MB of model files from this site. Your image is never uploaded. You can turn it off under More settings.
Tip: Check the numeric columns before you download. One misread character makes a column text.
