|Convert CSV files into a SQLite database|
A browser extension with 3.5k+ users.
It transforms raw
csv data into a simple
html table, and shows it online in the same tab.
When quickly looking through csv data files online, you either have to:
CSV Reader allows you to look at the data formatted as a table, so you can make decisions faster.
CSV Reader detects if the current tab is a
.csv page (correctly most of the time).
The user can select some settings in a popup to modify the output.
NEW: The extension now stores user settings per url for the next time you browse the same file.
NEW: The extension now stops
csv files from downloading (it modifies the response headers) so you can parse them in-browser. If you want to download the file just
cmd+s), even in the parsed
It offers different options (see images and examples below):
csvdata into a table, nicely formatted so it's easy to scan.
csvdata but rainbow-color it to make it easier to read (inspired by the Rainbow CSV VS Code extension).
It allows the user to input some settings:
||String||New column when this value is found|
||Boolean||Use the first line as the table header|
|Skip at the top||
||Number||Number of text lines to leave untouched at the top|
|Links in text||
||Boolean||Look for links in data and make them clickable|
.csv data file online. You can try this csv sample dataset.
Click on the CSV Reader extension icon.
In the popup, input the config options: separator, title row, etc. (In the example dataset,
| (pipe) as the separator, and check the title line option).
To go back to the raw data, click the "Reset" button on the extension popup:
If this extension was useful to you in any way, please consider leaving a 5-star review.
It will take you less than a minute, and will greatly help reach new audiences.
Thank you very much!
Suggestions and PRs are welcome, of course. This is (roughly) the dev process:
extension/content_scripts/csv_reader.js contains all the parse and output logic. The
browser.tabs queries use Promises, supported in Firefox but not in Chrome, so the extension loads a polyfill for this.
extension/popup/popup.js manages the user input logic, messaging to the main content script, and custom CSS inserts.
To load the unpacked, test extension:
extension/folder. Make sure the polyfill is in
To build and pack the extension, I use
web-ext too. It builds the
extension folder and creates a
.zip file inside
That's it, there is no further compiling or building process, for now at least.
Some features I'd like to work on (help appreciated):
.csvfiles from downloading, and instead open them in browser so thay can be converted.
