Convert BMP to CSV
Convert BMP to CSV to pull values out of an uncompressed scan or capture of a table into a data file.
Convert BMP to CSV to pull values out of a table that exists as a picture in an old format and collect them into a data file. BMP is what scanners and software from years ago tend to produce.
What happens when you convert BMP to CSV
Recognised rows and columns go into a delimited text file that opens in a spreadsheet and is accepted by imports. Neither the picture nor its palette reaches the result; the values do.
BMP stores an image without compression, so the text carries none of the smeared artefacts of a resaved JPG, and a crisp scan of a form reads well. Other things get in the way: a skewed sheet, shadows along the edges, and the dirty background of a photocopy, which cost you part of the values.
- Values from the table on the picture land in rows of the file.
- Borders, colours, and fonts of the source do not carry over.
- A picture with no readable wording gives no result: the conversion ends with an error.
How to convert BMP to CSV
- Upload your image in BMP.
- Select CSV as the result format.
- Start the conversion.
- Open the file and check the values against the source picture.
Where such pictures come from
- Work through an archive of scans once saved in BMP and take the tables out of them.
- Pull data out of a report that a plant-floor program exports as a picture.
- Move a form scanned without compression for quality into your records.
- Digitise a printout from a system that offers printing to a file but no export.
- Collect values from old documentation kept as images.
Similar directions
- A screenshot of a table is handled by the PNG to CSV converter.
- A photo of a paper form goes through the JPG to CSV converter.
- When the table sits in a PDF, the PDF to Excel (XLSX) converter is more accurate.
FAQ
Why does BMP read better than a resaved JPG?
BMP has no compression artefacts, so letter edges stay sharp. If the scan itself is skewed or faint, the source format no longer saves it.
What about a multi-page document?
Every picture is handled on its own, so convert the pages one by one and merge the files afterwards.
Does the result need checking?
Yes, compare the values with the picture: on a faint scan digits read worse than the rest of the text.
